Two Cases of Secondary Intracranial Hypotension
The unique symptom of intracranial hypotension (IH) is an orthostatic headache caused by low cerebrospinal fluid (CSF) pressure and is not so rare. IH results from loss of CSF caused by a dural defect in the spine, cranial vault, or skull base. The classic orthostatic headache commences within 15 minutes, but occasionally symptoms last up to several hours, after standing or upright sitting posi...
متن کاملCerebral angiographic findings of spontaneous intracranial hypotension.
We report a case of spontaneous intracranial hypotension that underwent cerebral angiography. The angiogram showed prominence of the veins and venous phase of the angiogram. This is thought to be secondary to decreased intracranial pressure and subsequent dilation of the venous system to attempt to replace the lost intracranial CSF volume. In situations in which the typical clinical presentatio...
متن کاملIntracranial cavernous hemangiomas: neuroradiologic review of 36 operated cases.
Neuroradiologic studies in 36 cases of histologically verified intracranial cavernous hemangiomas were reviewed. Radionuclide brain scans were positive in 17 of 19 examinations. Angiography, performed in 35 cases, usually showed an avascular area with absent or moderate mass effect. Capillary blush and/or early draining veins, often mentioned in single case reports, were observed in only seven ...
متن کاملSpontaneous intracranial hypotension: spinal MR findings.
We report three patients with spontaneous intracranial hypotension in whom spinal MR imaging revealed ventral extradural fluid collections that were centered at the cervicothoracic junction in two patients and extended throughout the entire spine in the third patient. These spinal fluid collections most likely resulted from the accumulation of CSF at the site of dural leakage. Knowledge of this...
متن کاملPostsurgical intracranial hypotension: diagnostic and prognostic imaging findings.
BACKGROUND AND PURPOSE CSF loss with consecutive intracranial hypotension has been discussed as a possible pathogenetic mechanism in poor clinical outcome after uneventful neurosurgery and appears to be correlated to specific imaging findings. The purpose of this study was to describe the clinical and imaging findings of symptomatic intracranial hypotension likely induced by wound suction drain...
