Intracranial hypotension syndrome: a comprehensive review

Teaching NeuroImages: Intracranial hypotension in a patient with Marfan syndrome.

An 18-year-old man with Marfan syndrome and migraine headaches presented with acute worsening of headaches with postural changes following spinal fusion surgery for scoliosis. Lumbar spine MRI done before surgery showed diffuse dural ectasia (figure 1). Brain MRI after surgery showed distended transverse and sagittal dural venous sinuses and an enlarged pituitary gland suggesting intracranial h...

Intracranial Anatomical Triangles: A Comprehensive Illustrated Review

There are multiple anatomical triangles of the skull base. However, to our knowledge, there has been no comprehensive review of these geometric landmarks. To allow for a safe and consistent approach to lesions of the skull base such as those near the internal carotid artery, internal acoustic meatus, and cavernous sinus, a comprehensive review of the variations with illustrations is required. T...

Intracranial hypotension.

The authors present the case of a 55-year-old man suffering from intractable spontaneous intracranial hypotension, in whom conservative treatment with 19 weeks of bed rest was not effective. In this period the patient twice underwent surgery for bilateral chronic subdural hematoma, a complication of spontaneous intracranial hypotension. Conventional radionuclide cisternography, magnetic resonan...

Pathophysiology and management of spontaneous intracranial hypotension--a review.

Spontaneous Intracranial Hypotension is a syndrome involving reduced intracranial pressure secondary to a dural tear which occurs mostly due to connective tissue disorders such as Marfans Syndrome, and Ehler Danlos Syndrome. Patients with dural ectasias leading to CSF leakage into the subdural or epidural space classically present with orthostatic headaches and cranial nerve deficits mostly see...
