Angiographic features of spontaneous intracranial hypotension.
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 enlargement of cortical and medullary veins. The angiographic findings were diagnostic of spontaneous intracranial hypotension and consistent with the Monro-Kellie hypothesis.
