The purpose of this study is to evaluate imaging and histopathologic findings including the immunohistochemical characteristics of invasive micropapillary carcinoma (IMPC) of the breast.
Twenty-nine patients diagnosed with IMPC were included in the present study. Mammographic, sonographic, and magnetic resonance imaging (MRI) findings were analyzed retrospectively according to the American College of Radiology Breast Imaging Reporting and Data System lexicon. 18F-fluorodeoxyglucose positron emission tomography-computed tomography (PET-CT) findings were also evaluated. Microscopic slides of surgical specimens were reviewed in consensus by two pathologists with a specialty in breast pathology.
Most IMPCs presented as a high density irregular mass with a non-circumscribed margin associated with microcalcifications on mammography, as an irregular hypoechoic mass with a spiculated margin on ultrasound, and as irregular spiculated masses with washout patterns on MRI. PET-CT showed a high maximum standardized uptake value (SUVmax) (mean, 11.2). Axillary nodal metastases were identified in 65.5% of the patients. Immunohistochemical studies showed high positivities for estrogen receptor and c-erbB-2 (93.1% and 51.7µ, respectively).
Even though the imaging characteristics of IMPCs are not distinguishable from typical invasive ductal carcinomas, this tumor type frequently results in nodal metastases and high positivities for both estrogen receptor and c-erbB-2. The high SUVmax value that is apparent on PET-CT might be helpful in the diagnosis of IMPC.

Between January 1998 and May 2004, 17 PTs and 14 MTs were pathologically confirmed at our institution. The preoperative mammography (n = 26) and sonography (n = 28) were analyzed by three radiologists according to BI-RADS.
On mammography, a mass was not detected in eight patients with PT and in one patient with MT (57% vs. 8%, respectively, p = 0.021), which was statistically different. The other findings on mammography and sonography showed no statistical differences between the PT and MT, although the numerical values were different. When the lesions were detected mammographically, an irregularly shaped mass with a spiculated margin was more frequently found in the MT than in the PT (100% vs. 83%, respectively, p = 0.353). On sonography, all 28 patients presented with a mass and most lesions showed as not being circumscribed, hypoechoic masses with an echogenic halo. Surrounding tissue changes and posterior shadowing were more frequently found in the MT than in the PT (75% vs. 50%, respectively, p = 0.253, 58% vs. 19%, respectively, p = 1.000). An oval shaped mass was more frequently found in the PT than in the MT (44% vs. 25%, respectively; p = 0.434).
PT and MT cannot be precisely differentiated on mammography and sonography. However, the absence of a mass on mammography or the presence of an oval shaped mass would favor the diagnosis of PT. An irregularly shaped mass with surrounding tissue change and posterior shadowing on sonography would favor the diagnosis of MT and also a less favorable prognosis.

To compare sonography and mammography in terms of their diagnostic value in breast cancer cases which initially presented as an axillary mass without a palpable mass or other clinical symptoms.
Materials and Methods
Seven patients with enlarged axillary lymph nodes who first presented with no evidence of palpable breast lesions and who underwent both mammography and sonography were enrolled in this study. In six of the seven, the presence of metastatic adenocarcinoma was confirmed preoperatively by axillary needle aspiration biopsy; in four, subsequent sonographically-guided breast core biopsy performed after careful examination of the primary site indicated that primary breast cancer was present. In each case, the radiologic findings were evaluated by both breast sonography and mammography.
Breast lesions were detected mammographically in four of seven cases (57%); in three of the four, the lesion presented as a mass, and in one as microcalcification. In three of these four detected cases, fatty or scattered fibroglandular breast parenchyma was present; in one, the parenchyma was dense. In the three cases in which lesions were not detected, mammography revealed the presence of heterogeneously dense parenchyma. Breast sonography showed that lesions were present in six of seven cases (86%); in the remaining patient, malignant microcalcification was detected at mammography. Final pathologic examination indicated that all breast lesions except one, which was a ductal carcinoma in situ, with microinvasion, were infiltrating ductal carcinomas whose size ranged from microscopic to greater than 3 cm. At the time of this study, all seven patients were alive and well, having been disease free for up to 61 months after surgery.
In women with a palpable axillary mass confirmed as metastatic adenocarcinoma, breast sonography may be a valuable adjunct to mammography.

Foreign body granuloma is a reaction to either a biodegradable substance or inert material. In a breast cancer patient who had undergone an excision or mastectomy with axillary clearance, a foreign body granuloma in the axilla may be misinterpreted as an axillary lymph node. We report our experience with a case of cotton-ball granuloma of the axilla in a breast cancer patient, which mimics a lymph node radiologically from the CT scan, mammogram and ultrasonography. Following biopsy and excision, the mass was diagnosed histologically as a foreign body granuloma.

Among women under the age of 40, screening mammography examinations are not performed routinely. An ultrasonography scan is considered to be a basic breast imaging examination among younger women. The purpose of this study was to analyze mammography images, as well as to evaluate the usefulness and role of mammography in breast cancer diagnostic processes in women of up to 45 years, based on own experience.
A retrospective analysis of mammography images, including 144 cases of breast cancer diagnosed in the group of 140 women of 45 years of age. All the patients underwent pre-treatment mammography and surgery procedure. The images were evaluated in accordance to BIRADS criteria. Lesions detectable in mammography were grouped as follows: • spiculated mass; • non-microcalcified oval/round mass; • microcalcified mass (regardless of shape); • microcalcifications; • architectural distortion; • breast tissue asymmetry.
The most common mammographic symptom was solid tumor (41%), followed by microcalcified tumors (20.8%). Clusters of microcalcifications constituted 17.4% of mammography findings. In 4.9% of mammography scans, examination did not reveal any pathological lesions.
Breast cancer mammograms of women aged up to 45 years do not differ from diagnostic pictures of breast cancer in older women.
The diagnostic appearance of breast cancer in 1/3 of the patients involved microcalcifications detectable only on mammograms.
All the women with suspicion of breast cancer should have their mammography examinations performed, irrespective of ultrasonography scans.

Background. Numerous reports have demonstrated how postoperative intracranial granulomas can often mimic neoplasm clinically, radiologically, and even macroscopically. Herein we present an unusual case of postsurgical intracranial aseptic granuloma secondary to a chronic inflammatory reaction without any identifiable retained foreign body. Case Description. A 71-year-old patient started complaining of severe headache seven months after surgical excision of WHO Grade I right frontal falx meningioma. CT and MRI scans disclosed a contrast-enhanced lesion with diffuse mass effect in the previous surgical site. The lesion was resected; intraoperative finding and histological specimens led to the diagnosis of postoperative granuloma, likely expression of a glial reaction to the fluid absorbable hemostatics applied in the surgical site after meningioma excision. The possible granuloma-inducing materials and the timing of granuloma formation are discussed. Conclusion. A comprehensive analysis of clinical and neuroradiological data, as well as results of blood tests including positive and negative acute phase proteins, is mandatory to raise the suspicion of postoperative granuloma. The treatment options should be evaluated on a case-by-case basis, with a conservative attitude being the one of choice only for patients without progressive neurological deficit. Alternatively, aggressive surgical treatment and histopathological examination should be advocated.
Sonography is an attractive supplement to mammography in breast cancer screening because it is relatively inexpensive, requires no contrast-medium injection, is well tolerated by patients, and is widely available for equipment as compared with MRI. Sonography has been especially valuable for women with mammographically dense breast because it has consistently been able to detect a substantial number of cancers at an early stage. Despite these findings, breast sonography has known limitations as a screening tool; operator-dependence, the shortage of skilled operators, the inability to detect microcalcifications, and substantially higher false-positive rates than mammography. Further study of screening sonography is still ongoing and is expected to help establish the role of screening sonography.

The purpose of this study was to correlate sonographic and mammographic findings with prognostic factors in patients with node-negative invasive breast cancer.
Sonographic and mammographic findings in 710 consecutive patients (age range 21–81 years; mean age 49 years) with 715 node-negative invasive breast cancers were retrospectively evaluated. Pathology reports relating to tumour size, histological grade, lymphovascular invasion (LVI), extensive intraductal component (EIC), oestrogen receptor (ER) status and HER-2/neu status were reviewed and correlated with the imaging findings. Statistical analysis was performed using logistic regression analysis and intraclass correlation coefficient (ICC).
On mammography, non-spiculated masses with calcifications were associated with all poor prognostic factors: high histological grade, positive LVI, EIC, HER-2/neu status and negative ER. Other lesions were associated with none of these poor prognostic factors. Hyperdense masses on mammography, the presence of mixed echogenicity, posterior enhancement, calcifications in-or-out of masses and diffusely increased vascularity on sonography were associated with high histological grade and negative ER. Associated calcifications on both mammograms and sonograms were correlated with EIC and HER-2/neu overexpression. The ICC value for the disease extent was 0.60 on mammography and 0.70 on sonography.
Several sonographic and mammographic features can have a prognostic value in the subsequent treatment of patients with node-negative invasive breast cancer. Radiologists should pay more attention to masses that are associated with calcifications because on both mammography and sonography associated calcifications were predictors of positive EIC and HER-2/neu overexpression.
A spiculated mass on a mammogram is highly suggestive of malignancy. We report the case of a 32-year-old woman with a radial sclerosing lesion that mimicked breast cancer on mammography. She visited her physician after palpating a lump in her left breast. Mammography showed architectural distortion in the upper inner quadrant of the left breast. Ultrasonography showed a low echoic area with an ambiguous boundary. Core needle biopsy was performed because of the suspicion of malignancy. Histological examination did not reveal any malignant cells. After 6 months, the breast lump became larger and the patient was referred to our hospital. Mammography performed in our hospital showed a spiculated mass, and therefore mammotome biopsy was performed. Histological examination revealed dense fibroelastic stroma with a wide variety of mastopathic changes, leading to a diagnosis of a radial sclerosing lesion. One year after the biopsy, the lump on her left breast had disappeared and mammography showed no spiculated mass.

Male breast cancer is an uncommon disease of uncertain etiology. We describe a 66-year-old man who presented with a palpable mass in the left breast with associated nipple inversion. Mammographic images demonstrated a spiculated mass within the subareolar left breast at the palpable area of concern. Sonographic evaluation demonstrated a hypoechoic mass within the subareolar left breast at the location of the mammographic abnormality. The patient underwent an excisional biopsy and was subsequently diagnosed with high-grade invasive ductal carcinoma, the most common histologic type of carcinoma identified in men.
Rationale and Objectives
Although spiculation level of breast mass boundary is a primary sign of malignancy for the mass detected on mammograms, developing an automated computer scheme to detect mass spiculation level and quantitatively evaluating the performance of the scheme is a difficult task. The objective of this study is to (1) develop and test a new scheme to improve mass segmentation and detect mass boundary spiculation level, and (2) assess the scheme performance using a relatively large image dataset.
Materials and Methods
This fully-automated scheme includes three image processing steps. The first step applies the maximum entropy principle in the selected region of interest (ROI) after correcting the background-trend to enhance the initial outlines of the masses. The second step uses an active contour model to refine the initial outlines. The third step detects and identifies spiculated lines connected to the mass boundary using a special line detector. A quantitative spiculation index is computed to assess the degree of spiculation levels. To develop and evaluate this automated scheme, we selected 211 ROIs depicting masses that were extracted from a publicly available image database. Among these ROIs, 106 depict “circumscribed” mass regions and 105 involve “spiculated” mass regions. The scheme performance was evaluated using the receiver operating characteristic (ROC) analysis method.
The computed area under ROC curve when applying the scheme to the dataset is 0.701 ± 0.027. By setting up a threshold at spiculation index = 5.0, the scheme achieves the overall classification accuracy of 66.4% with 54.3% sensitivity and 78.3% specificity, respectively.
We developed a new computer scheme with a number of unique characteristics to detect spiculated mass regions and applied a simple spiculation index to quantify mass spiculation levels. Although this quantitative index can be used to classify between the spiculated and circumscribed masses, the results also suggest that automated detection of mass spiculation levels remains a technical challenge.

Injected liquid silicone continues to be employed by unscrupulous practitioners in many parts of the world for the purpose of breast augmentation. Complications vary; however, inflammation, foreign body reaction, and granuloma formation often lead to painful and disfigured breasts. Furthermore, migrations of silicone to remote tissues cause additional problems. We present a review of cases and propose an updated algorithm for the diagnosis and management silicone mastitis. We describe two representative cases of mastitis cause by injected liquid silicone. Patients uniformly developed inflammation and granuloma formation causing painful and disfigured breasts. Each patient required bilateral mastectomy and breast reconstruction. Although injection of liquid silicone has been condemned by the legitimate medical community for the purpose of breast augmentation, it continues to be illicitly performed and there exists a sizable patient population suffering from the complications of this procedure. Accurate identification requires a high index of suspicion in patients presenting with firm and painful breasts. An aggressive management strategy is recommended in the setting of silicone mastitis due to the risk of obscuring malignancy.

Surgical suture material is usually inert and nontoxic and causes minimal inflammation of tissue. However, foreign body reactions to various suture types can lead to granuloma, abscess, or even sinus formation. We report an elderly female who was incidentally detected to have a mass protruding from the incision site which was confirmed histopathologically a chronic granulomatous reaction to non absorbable suture. The foreign body granulomatous reaction to suture material in the setting of pacemaker implantation has not been described in the literature. We also discuss the existing literature on this underrecognised entity.

Two cases of lymphoid malignancy involving the breast are herein presented. Both patients were admitted with a palpable breast mass. Ultrasound demonstrated hypoechoic, ill-defined lesions of the breast in both patients; mammogram also showed spiculated breast densities. Both patients underwent core biopsy, which revealed lymphomatous cells. Total-body evaluation was also performed by computed tomography and positron emission tomography/computed tomography revealing no other fluorodeoxyglucose-avid foci in the first case and supra and subdiaphragmatic disease in the second one.

Foreign body granuloma is a tissue reaction for retained foreign bodies after skin-penetrating trauma. Detection of retained foreign bodies can be extremely difficult when the patients present with non-specific symptoms such as pain and/or swelling without recognizing a previous trauma. We report three patients of foreign body granulomas in the lower extremities with emphasis placed on their unique clinical and radiological features. The involved sites were the foot, posterior thigh, and posterior lower leg, with wooden splinters in two patients and a fragment of tile in one. Plain radiographs could not reveal the existence of foreign bodies. Magnetic resonance imaging (MRI) showed foreign bodies as low intensities on both T1- and T2-weighted images in two patients, and the surrounding reactive lesion as low to iso intensities on T1- and high intensities on T2-weighted images in all the patients. The peripheral areas of the lesion were strongly enhanced after gadolinium injection. Ultrasound sonography could clearly visualize a foreign body as an echogenic area with posterior acoustic shadowing in one patient. The surrounding ring-like reactive lesion is easily mistaken for a soft tissue neoplasm when foreign bodies are not identified. The key to arriving at the correct diagnosis is to clarify the previous trauma and to identify foreign bodies with low signal intensities on both T1- and T2-weighted images and/or the characteristic ring-like enhancement on MRI. It is also necessary to rule out a foreign body granuloma whenever we see patients with a soft tissue tumor in the extremities, irrespective of their previous trauma history.

Soft tissue foreign bodies are a common cause of orthopedic consultation in emergency departments. It is difficult to confirm their existence because conventional radiology only detects radio-opaque foreign bodies. Sonography can be a useful diagnostic method. The aim of this study is to evaluate diagnostic accuracy of sonography in detection and localization of non-opaque foreign bodies.
We evaluated 47 patients with suspected foreign body retention in soft tissues by 10 MHz linear array transducer. A single radiologist performed all examinations with 6 years' experience in musculoskeletal Sonography. We detected and localized the presence of the foreign body in the soft tissue as guidance for facilitating the surgery.
We detected soft tissue foreign body in 45 cases as hyperechoic foci. Posterior acoustic shadowing was seen in 36 cases and halo sign was seen in 5 cases due to abscess or granulation tissue formation. Surgery was performed in 39 patients and 44 foreign bodies were removed.
Sonography is a useful modality in detection and localization of radiolucent foreign bodies in soft tissue which can avoid misdiagnosis during primary emergency evaluation.
The purpose of this project was to determine whether Contrast Limited Adaptive Histogram Equalization (CLAHE) improves detection of simulated spiculations in dense mammograms. Lines simulating the appearance of spiculations, a common marker of malignancy when visualized with masses, were embedded in dense mammograms digitized at 50 micron pixels, 12 bits deep. Film images with no CLAHE applied were compared to film images with nine different combinations of clip levels and region sizes applied. A simulated spiculation was embedded in a background of dense breast tissue, with the orientation of the spiculation varied. The key variables involved in each trial included the orientation of the spiculation, contrast level of the spiculation and the CLAHE settings applied to the image. Combining the 10 CLAHE conditions, 4 contrast levels and 4 orientations gave 160 combinations. The trials were constructed by pairing 160 combinations of key variables with 40 backgrounds. Twenty student observers were asked to detect the orientation of the spiculation in the image. There was a statistically significant improvement in detection performance for spiculations with CLAHE over unenhanced images when the region size was set at 32 with a clip level of 2, and when the region size was set at 32 with a clip level of 4. The selected CLAHE settings should be tested in the clinic with digital mammograms to determine whether detection of spiculations associated with masses detected at mammography can be improved.

Intracranial foreign body granulomas are rarely reported. Clinical symptoms caused by foreign body granulomas can be noticed from months to many years after surgical procedure. The most common reported etiology is suture material. A 45-year-old woman was presented with grand mal epilepsy. She was operated for brain tumor 19 years ago. In CT scan, a round radio-dense mass resembling a tumor at anterior fossa was seen. She underwent craniotomy and resected a granuloma with cotton fibers surrounded by yellow capsule without residual or recurrent tumor. Granuloma can mimic intracranial meningioma and special attention should be paid not to leave cotton pledgets during operations.

Computer-aided diagnosis (CAD) for characterization of mammographic masses as malignant or benign has the potential to assist radiologists in reducing the biopsy rate without increasing false negatives. The purpose of this study was to develop an automated method for mammographic mass segmentation and explore new image based features in combination with patient information in order to improve the performance of mass characterization. Our previous CAD system, which used the active contour segmentation, and morphological, textural, and spiculation features, has achieved promising results in mass characterization. The new CAD system is based on the level set method, and includes two new types of image features related to the presence of microcalcifications with the mass and abruptness of the mass margin, and patient age. A linear discriminant analysis (LDA) classifier with stepwise feature selection was used to merge the extracted features into a classification score. The classification accuracy was evaluated using the area under the receiver operating characteristic curve. Our primary data set consisted of 427 biopsy-proven masses (200 malignant and 227 benign) in 909 regions of interest (ROIs) (451 malignant and 458 benign) from multiple mammographic views. Leave-one-case-out resampling was used for training and testing. The new CAD system based on the level set segmentation and the new mammographic feature space achieved a view-based Az value of 0.83±0.01. The improvement compared to the previous CAD system was statistically significant (p=0.02). When patient age was included in the new CAD system, view-based and case-based Az values were 0.85±0.01 and 0.87±0.02, respectively. The performance of the new CAD system was also compared to an experienced radiologist’s likelihood of malignancy rating. When patient age was used in classification, the accuracy of the new CAD system was comparable to that of the radiologist (p=0.34). The study also demonstrated the consistency of the newly developed CAD system by evaluating the statistics of the weights of the LDA classifiers in leave-one-case-out classification. Finally, an independent test on the publicly available digital database for screening mammography (DDSM) with 132 benign and 197 malignant ROIs containing masses achieved a view-based Az value of 0.84±0.02.

We describe a case of actinomycosis of the gallbladder mimicking carcinoma. Sonography showed a hypoechoic mass replacing gallbladder lumen and engulfing a stone; contrast-enhanced computed tomography showed a heterogeneously enhanced thickened gallbladder wall with subtle, disrupted luminal surface enhancement, which formed a mass. As a result of the clinical and radiologic presentation, our impression was of gallbladder carcinoma. Actinomycosis should be included in the differential diagnosis when sonography and computed tomography findings show a mass engulfing the stone in the gallbladder and extensive pericholecystic infiltration with extension to neighboring abdominal wall muscle.

The radiologic and clinical findings of foreign bodies in the chest of children are well recognized. Foreign bodies in adults are infrequent, however, and the radiologic findings of these unusual circumstances have rarely been described. We classified various thoracic foreign bodies into three types according to their cause: Type I, Aspiration, Type II, Trauma or Accident; Type III, Iatrogenic. This pictorial essay will illustrate the radiologic findings and consequences of thoracic foreign bodies in adults, which have rarely been described in the radiologic literature. The clinical significance of thoracic foreign bodies will be also be discussed.

Pulse granuloma is a distinct oral entity characterized as a foreign body reaction occurring either centrally or peripherally. It is usually seen in the periapical or in the sulcus area. Occasionally the lesions occur in the wall of the cyst, commonest being the inflammatory odontogenic cyst. Histologically, they present as eosinophilic hyaline mass with giant cell inclusions and inflammatory cells. They may show different histological characteristics, possibly related to the length of time in the tissue. Adequate recognition is important to avoid misdiagnosis. Many authors suggest that pulse granuloma results due to implantation of food particles of plant or vegetable origin into the tissue following tooth extraction. This paper aims to report a case of pulse granuloma associated with keratocystic odontogenic tumor with its histochemical and polarizing microscopic features and discuss on etiopathogenesis of pulse granuloma.

Eccrine spiradenomas are rare, benign, cutaneous tumors that originate in the sweat glands. Eccrine spiradenomas in the breast are very rare and only a few cases have been reported. We report here on the case of a 47-year-old woman with superficial masses in the breast and these masses had gradually increased in size during follow-up. They were confirmed to be an eccrine spiradenoma on pathologic examination. There have been a few reports about the radiologic findings of eccrine spiradenomas of the breast. This is the first case of an eccrine spiradenoma in the breast that was characterized by multiple imaging modalities, including mammography, ultrasonography and MRI. The lesion in our patient was first diagnosed as an epidermal inclusion cyst based on the imaging findings and the mass's superficial location. Although the mammographic and ultrasonographic imaging findings of eccrine spiradenomas and epidermal inclusion cysts are similar, the MRI findings are different between epidermal inclusion cysts and eccrine spiradenomas. Eccrine spiradenomas should be considered in the differential diagnosis of cutaneous and subcutaneous lesions of the breast.

Myoid hamartomas of the breast are extremely rare breast lesions, with a poorly understood pathogenesis. We describe the case of a 38-year-old premenopausal woman who presenting with a mass in the left breast. Mammography revealed an oval mass that was partly indistinct, and ultrasonography showed a hypoechoic mass with a slightly irregular margin. Bilateral breast dynamic magnetic resonance imaging was performed for a more detailed evaluation. The images showed rapid initial enhancement and a microlobulated margin. Because the suspicion of malignancy was strong at that time, core needle biopsy was performed. Histologically, the tumor was identified as fibroadenoma. A case of myoid hamartoma of the breast that proved difficult to diagnose is reported, and discussed with reference to the literature.

Idiopathic granulomatous lobular mastitis (IGLM) is a rare chronic inflammatory disease of the breast with obscure etiology that mimics invasive carcinoma both clinically and radiologically. The treatment of IGLM remains controversial. The aim of proper management is to use a combination of medical and surgical treatment of this benign condition to achieve a good cosmetic result and low recurrence rate.
A retrospective analysis of 19 patients with IGLM is performed based on the findings of clinical, radiological, and pathological examinations. The results of two treatments are presented: medical treatment with oral corticosteroids, and consecutive surgical excision after a follow-up period of 20 months (range, 6-75 months).
The majority of patients treated in this paper were young (mean, 34 years) parous women with a history of hormonal medication use. The main clinical finding is large, irregular, and painful mass. Hypoechoic lobulated, irregular tubular or oval shaped masses had been imaged by ultrasound. Mammographic findings were an ill-defined mass, enlarged axillary lymph nodes, asymmetric density, and architectural distortion. Diagnoses of IGLM had been established by cytological or histological examination. Symptoms subside and inflammatory changes regressed with medical treatment. The remaining lesions were excised by consecutive breast conserving surgery. The disease recurred in one patient during the follow-up period.
IGLM is an inflammatory breast disease found in young women who present with a large painful irregular mass, which mimics carcinoma, as a physical change. Breast imaging modalities are not helpful to differentiate IGLM from invasive cancer. The correct diagnosis is established by cytological or histological examination. Medical treatment with corticosteroids provides significant regression of the inflammatory disease, allowing more conservative surgery. Consecutive surgical excision of the remaining lesions with good cosmetic results provides definitive treatment and reduces the risk of recurrence.
