Cortical Subarachnoid Hemorrhage in Behcet's Disease

Cortical subarachnoid hemorrhage (cSAH) can be resulted from by a wide variety of causes. A cSAH probably associated with Behcet's disease is herein reported for the first time.

A 58-year-old male with stable Behcet's disease evaluated for sudden onset headache. Emergency computed tomography disclosed cSAH in the left frontal sulci. A ruptured middle cerebral artery cortical branch aneurysm was found. Surprisingly, this aneurysm obliterated completely after diagnostic catheter angiography.

This case highlights three important points; First, non-mycotic (non-infectious) distal cerebral artery aneurysms may rarely cause cSAH. Second, distal dissecting aneurysms may rarely become obliterated after diagnostic cerebral angiography. Third, such aneurysms may be one of the long-term consequences of vascular inflammation in Behçet's disease.
