Reversible cerebral vasoconstriction in spontaneous intracranial hypotension.
Myelography showed an opening pressure of 0 cm H2O and multiple thoracic meningeal diverticula in a 52-year-old woman suffering from orthostatic headaches of instantaneous onset. MR-angiography showed severe segmental arterial stenosis of the anterior and posterior circulation, which resolved over a 4-day period following an epidural blood patch. Spontaneous intracranial hypotension should be considered in the differential diagnosis of reversible cerebral vasoconstriction.
