Intracranial hypertension and intracranial hypotension are on the opposite end of the intracranial pressure spectra. It is extremely uncommon for both to cause headache in the same patient within a span of several days. This report describes a young man with intracranial hypertension who developed a severe excruciating headache due to intracranial hypotension after a diagnostic lumbar puncture....

Intracranial hypotension syndrome typically occurs spontaneously or iatrogenically. It can be associated with headache, drowsy mentality and intracranial heamorrhage. Iatrogenic intracranial hypotension can occur due to dural pucture, trauma and spine surgery. Treatment may include conservative therapy and operation. We report a case of a 54-year-old man who was successfully treated with epidur...

Intracranial hypotension is characterized by a postural headache which is relieved in a supine position and worsened in a sitting or standing position. Although less commonly reported than postural headache, sixth nerve palsy has also been observed in intracranial hypotension. The epidural blood patch (EBP) has been performed for postdural puncture headache, but little is known about the proper...

Spontaneous intracranial hypotension is frequently idiopathic. The authors report on a patient presenting with symptomatic intracranial hypotension caused by a transdural calcified thoracic disc herniation. Cranial magnetic resonance (MR) imaging revealed classic signs of intracranial hypotension, and a combination of spinal MR and computerized tomography myelography confirmed a mid-thoracic tr...

Although few patients with spontaneous intracranial hypotension develop cerebral venous thrombosis, the association between these two entities seems too common to be simply a coincidental finding. We describe two cases of spontaneous intracranial hypotension associated with cerebral venous thrombosis. In one case, extensive cerebral venous thrombosis involved the superior sagittal sinus and mul...

INTRACRANIAL hypotension is an important cause of new daily persistent postural headaches. Among the causes of intracranial hypotension, many cases are due to spontaneous cerebrospinal fluid (CSF) leak, often associated with an underlying generalized connective tissue disorder. Intracranial hypotension may also be due to dural puncture after epidural catheter positioning. Most cases of intracra...

The association of spontaneous intracranial hypotension with cerebral venous sinus thrombosis is rare. We report here a case of extensive cerebral venous sinus thrombosis involving three sinuses following spontaneous intracranial hypotension. The patient presented no other thrombotic risk factors except for spontaneous intracranial hypotension. This case adds to the evidence that spontaneous in...

Intracranial hypotension (IH) is a clinical and radiological syndrome manifested by decrease in the volume or pressure of cerebrospinal fluid caused various reasons. Orthostatic headaches are one main manifestations syndrome, magnetic resonance imaging (MRI) considered to be “gold standard” radiation diagnostics. Increased awareness radiologists, neurologists, neurosurgeons about this pathology...

The outcome of spontaneous intracranial hypotension has been unpredictable. The results of initial MRI were correlated to outcome of treatment in 33 patients with spontaneous intracranial hypotension. A good outcome was obtained in 25 (97%) of 26 patients with an abnormal MRI vs only 1 (14%) of 7 patients with a normal MRI (p = 0.00004). These findings show that normal initial MRI is predictive...

The imaging characteristics of spontaneous intracranial hypotension have been well described in the clinical and imaging literature. We present a case of spontaneous intracranial hypotension with typical clinical and laboratory features that were thought to be suspicious for a ruptured aneurysm. Blood in the CSF in conjunction with headaches led to cerebral angiography that showed diffuse enlar...
