Cerebral 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 presentation is not present and additional examinations such as cerebral angiography are performed, these findings may be helpful to direct the physicians involved toward the correct diagnosis.
