Abstract
The artery of Percheron is a single dominant vessel of posterior cerebral artery which supplies the thalamus bilaterally. It is a rare variant of arterial supply to the paramedian thalami. The classical triad of presentation of artery of Percheron occlusion is vertical gaze palsy, memory impairment, and alteration of mental status. Here we report a case of artery of Percheron occlusion where the patient presents with classic features of thalamic infarction associated with the midbrain involvement evidenced by the presence of bilateral hemiparesis. When compared to the typical thalamic infarction alone, the prognosis is worse when midbrain is also affected.
