Abstract

We describe a case of disruption of the blood-brain barrier (BBB) by nonionic, low osmolality contrast medium after abdominal angiography. One plausible explanation of this event is that acute hypertension during angiography may have increased the BBB permeability, allowing the contrast medium to leak across it.
