A 65-year old man with atrial fibrillation presented with the acute onset of a global aphasia and right hemiplegia.

Outline the Infarction                         Show the Distribution of the Perforators to the Basal Ganglia (BG)

CT Scan of the brain (day 3). Note the large hypodensity involving the entire middle cerebral artery territory as well as the deeper basal ganglia. The fact that the basal ganglia are involved denotes that the infarction involved the proximal middle cerebral artery stem, before the take off of the small perforating vessels which supply the basal ganglia.
