Spontaneous dural tear leading to intracranial hypotension and tonsillar herniation in Marfan syndrome: a case report



We describe the case of a 38 year old male with Marfan syndrome who presented with orthostatic headaches and seizures.

Case Presentation

The patient was diagnosed with Spontaneous Intracranial Hypotension secondary to CSF leaks, objectively demonstrated by MR Myelogram with intrathecal contrast. Epidural autologus blood patch was administered at the leakage site leading to significant improvement.


Our literature search shows that this is the second reported case of a Marfan patient presenting with symptomatic spontaneous CSF leaks along with tonsillar herniation.


Spontaneous intracranial hypotension (SIH) is an under diagnosed entity that was first described by Schaltenbrand in 1938 [1]; however, a more objective description of SIH was later proposed as a "decrease in CSF pressure to less than 60 mm H2O associated with occipital headaches [2,3]". An emergency department based study estimated the annual incidence of SIH to be 5 per 100,000 [4]; this condition is twice as common in females [5].

A traumatic event and generalized connective tissue disorders (CTDs) are amongst the commonest etiologies for SIH. Among the CTDs, Marfan,[6-8] Ehlers-Danlos type II [9] and autosomal dominant polycystic kidney disease [10] are associated with spontaneous CSF leaks leading to SIH.

SIH can present in a variety of ways including orthostatic headache, diplopia, tinnitus, photophobia, hyperacusis and vomiting [11-13]. On clinical examination, bradycardia, nystagmus, Abducens nerve palsy and neck stiffness are common findings [14,15]. Radiologically, there are 5 characteristic features of SIH on MR imaging: 1. Subdural fluid collections; 2.Enhancement of pachymeninges; 3. Engorgement of venous structures; 4. Pituitary hyperemia; 5. Sagging of the brain (acronym: SEEPS) [16]. MR Myelography with intrathecal contrast is considered the imaging modality of choice to accurately locate the CSF leak [3].

We present a case of intracranial hypotension secondary to a spontaneous dural tear in an adult patient with Marfan syndrome.

Case Presentation

Our patient, a 38 year old male, diagnosed case of Marfan's syndrome, presented with complaints of orthostatic headaches and one episode of seizure. His current illness started 15 days ago with bilateral neck pain, which progressed to a holocranial headache which would get markedly worse on sitting, standing or bending forward and relived by lying down. These symptoms progressed over the past 2 weeks and on the day of presentation he suffered a generalized tonic - clonic seizure which prompted admission. There was no history of trauma.

On examination, our patient was hemodynamically stable and afebrile. He displayed characteristic marfanoid features including micrognathia, tall and lean stature, disproportionately long limbs and joint hypermobility. On detailed neurological examination, he was drowsy but arousable to vocal commands and had no signs of meningeal irritation. Cranial nerves, motor, sensory and cerebellar examination was unremarkable except for bilaterally up going plantars.

Routine blood tests were normal. MRI brain with contrast revealed pachymeningitis (Figure (Figure1a),1a), atlanto-axial subluxation, cerebellar tonsillar herniation and flattening of pontine surface (Figure (Figure1b).1b). Since the clinico-radiological findings were suggestive of spontaneous intracranial hypotension probably secondary to a dural tear, an MR myelogram study with intrathecal contrast was performed that demonstrated expansion of thecal sac, more marked in the lumbosacral region with multiple dilated out-pouchings in the sacral regions, S1-3, representing dural ectasias (Figure (Figure2a).2a). Accumulation of fluid in the posterior para-spinal muscles was also observed (Figure (Figure2b),2b), further strengthening the suspicion of CSF leaks.

An autologous epidural blood patch using 25 ml of blood was applied at L4/5 level. This procedure resulted in marked improvement and almost complete resolution of his symptoms over the next 96 hours. In the first 48 hours after the procedure, strict recumbent position was maintained. He was then discharged with instructions to gradually resume sitting posture from complete bed rest by adding one to two pillows under his head every day. This was continued until he was able to stand upright without headaches.

He was followed up regularly as an outpatient for the next 6 months with no evidence of any complications or recurrence and returned to normal baseline activity and lifestyle.


Spontaneous intracranial hypotension (SIH) is increasingly recognized as a clinically variable syndrome caused by non-traumatic CSF leaks. Connective tissue disorders (CTDs) like Marfan syndrome are the most important predisposing conditions.

There is only one case report in the literature that links spontaneous CSF leak complicated by tonsillar herniation in a Marfan patient [17]. This complication was also seen in our patient.

Tonsillar herniation is considered a part of the SIH complex and has been labeled as "acquired Chiari - Malformation I (CM-I)" [17]. Lack of awareness or erroneous diagnoses has been reported to lead to unnecessary surgical intervention such as suboccipital craniectomy for posterior fossa decompression in an attempt to treat intractable headaches thought to be caused by tonsillar herniation; only later was it realized that the real cause of headaches was SIH secondary to CSF leaks [17].

Amongst the major abnormalities detected on an MRI study, thickening of pachymeninges and engorgement of venous sinuses occur as a result of vascular dilation to compensate for the reduced CSF volume in accordance with the Monro-Kellie hypothesis [18].

A spectrum of treatment method exists to manage SIH. It is reported that bed rest relieves headache of ICH through reduced CSF pressure at the site of leakage allowing rapid healing of the meningeal defects [19]. Although widely accepted, this concept has been challenged by other investigators [20].

Attempts to increase CSF volume include oral and intravenous rehydration, increased salt intake and steroid therapy. Although there has been some clinical improvement in patients with these modes of therapies, conclusive studies proving efficacy are still awaited; in fact some studies have shown these measures to be of questionable use [21].

Epidural blood patches are generally considered a safe and effective option after bed rest and conservative management. It has been found that the procedure success rate is higher if it is performed at or within one interspace of the leak [22].

Surgical correction is required only when all the other measures have failed and a meningeal defect has been demonstrated. Simple ligation of the meningeal diverticula can achieve complete resolution of symptoms in 100% of patients [23].


Spontaneous intracranial hypotension is now being recognized as a fairly rare entity but is more commonly seen in settings of connective tissue disorders. However, general physicians and neurologists should be aware of this condition while providing consultations to patients with postural headaches. Proper education to physicians regarding the diagnosis, evaluation and management of SIH can save patients from embarking on invasive surgical procedures.
