  • Abstract
  • Look Inside

A 21-year-old man presented with sudden weak-ness and dysesthesia of his right limbs. Computer-ized tomography (CT) scan showed a low density area in the posterolateral part of the left thalamus. Right vertebral angiography revealed a small aneu-rysm at the P2 segment of the posterior cerebral artery. Magnetic resonance imaging (MRI) demon-strated intraaneurysmal clot and signal void in the residual lumen. There were no other lesion and no predisposing risk factors that produced cerebral ischemia. It was thougt that the aneurysm was the source of emboli resulting in thalamic infarction. The patient underwent a left subtemporal crani-otomy, and the aneurysm was clipped. Following surgery, there has been no recurrence of ischemic attacks. The diagnosis and the therapy were discussed, with reference to the literature.
