Abstract

The association of posterior cerebral artery(PCA) aneurysms with thalamic arteriovenous malformations(AVM) is very rare. This case is the first to describe a thalamic AVM fed by the P1 perforator of the PCA that was the anatomic origin of a ruptured cerebral aneurysm. A 45-year-old man presenting with semicomatose mental state underwent brain computed tomogram that demonstrated diffuse subarachnoid hemorrhage(SAH) in left ambient and quadrigeminal cistern. The aneurysm proved to arise from the proximal portion of AVM-feeding artery angiographically and surgically.
