1.  Bilateral hypertrophic olivary degeneration

2.  Hypothalamic glioma masquerading as craniopharyngioma 
Hypothalamic glioma account for 10-15% of supratentorial tumors in children. They usually present earlier (first 5 years of age) than craniopharyngioma. Hypothalamic glioma poses a diagnostic dilemma with craniopharyngioma and other hypothalamic region tumors, when they present with atypical clinical or imaging patterns. Neuroimaging modalities especially MRI plays a very important role in scrutinizing the lesions in the hypothalamic region. We report a case of a hypothalamic glioma masquerading as a craniopharyngioma on imaging along with brief review of both the tumors.

3.  Pseudo-Scimitar syndrome 
The pulmonary venous abnormalities are very rare and are difficult to diagnose. We present a case of middle age male who presented with cough and chest pain. Chest radiograph showed abnormal tortuous vessel in right lung. Computed tomographic angiography of chest demonstrated meandering anomalous right superior pulmonary vein.

5.  Tuberculosis of parotid gland masquerading parotid neoplasm 
Parotid gland involvement in tuberculosis is rare. We present a case of middle aged male presenting with parotid swelling for 1 year and diagnosed to have parotid tuberculosis on fine needle aspiration cytology. A brief review of radiological findings in tuberculous parotitis is discussed which can help in correct interpretation and timely diagnosis, and thus avoiding unnecessary parotidectomies.

6.  Comparison of helical and axial mode indirect computed tomographic venography in patients with pulmonary thromboembolism 
Objective:
To compare the helical and axial modes of indirect computed tomographic (CT) venography (CTV) for accuracy for diagnosing deep venous thrombosis (DVT) of the lower extremities as well as for their radiation burden in patients proven to have pulmonary thromboembolism (PTE) on CT pulmonary angiography (CTPA).
Subjects and Methods:
Of patients evaluated with CTPA for suspected acute PE, 20 of patients who were found to have PTE underwent both indirect CTV of the lower extremities and color Doppler examination. For indirect CTV, patients were randomly assigned to helical and axial modes. The CTV and Doppler findings were interpreted by two experienced radiologists who were blinded to the results of each other.
Results:
Out of total of 260 venous segments analyzed (130 venous segments each by helical or axial CTV), thrombi were seen in 43 venous segments (15 and 28 each by helical or axial CTV respectively). On comparison with Doppler, helical CTV had 82.35% sensitivity and 99.11% specificity, whereas axial CTV had 96.6% sensitivity and 100% specificity. The mean radiation dose was significantly higher for helical (1153.57 mgy.cm) as compared to axial mode CTV (806.28 mgy.cm) with P value of <0.0001.
Conclusion:
Axial CTV results in decreased radiation dose without significant change in the accuracy, as compared to helical CTV in the evaluation of DVT.

8.  Spontaneous esophageal-pleural fistula 
Spontaneous esophageal-pleural fistula (EPF) is a rare entity. We describe a case in a middle-aged female who presented with severe retrosternal chest pain and shortness of breadth. Chest computed tomography showed right EPF and hydropneumothorax. She was managed conservatively keeping the chest tube drainage and performing feeding jejunostomy. A brief review of the imaging finding and management of EPF is discussed.

9.  Superior and Inferior Ophthalmic Veins Thrombosis with Cavernous Sinus Meningioma 
Ophthalmic vein thrombosis is an extremely rare entity. We present a case of middle-aged female who presented with proptosis. Contrast-enhanced computed tomography and magnetic resonance imaging showed cavernous sinus meningioma with ipsilateral superior and inferior vein thrombosis. A brief review of the vascular involvement of the meningioma and ophthalmic vein thrombosis is presented along with the case.

12.  Transient splenial lesion: Further experience with two cases 
Transient splenial lesions (TSL) of the corpus callosum are uncommon radiologic findings that are seen in a number of clinical conditions with varied etiologies. They were first described a decade earlier in patients with epilepsy and hence were thought to be seizure or seizure therapy related. Subsequently, more cases were described by different observers in diseases with different etiologies, and the list is still increasing. Awareness of these lesions is necessary as they are an uncommon finding and have to be differentiated from other infective/noninfective causes. MRI is the imaging modality of choice as these lesions are not seen on routine noncontrast CT scan. The authors here describe two cases which showed TSL, with complete/partial resolution on follow-up scans. The authors also present a review of the literature.
