Abstract
The artery of Percheron is a rare vascular entity of cerebral circulation. High degree of suspicion is required to diagnose this condition. Artery of Percheron infarction should be considered in all patients presenting with sudden loss of consciousness. MRI shows a characteristic pattern of bilateral paramedian thalamic infarcts with or without midbrain involvement. We report a case of a 45-year-old man with acute bilateral thalamic infarcts. Occlusion of the vessel was presumably due to hyperhomocysteinemia. Key words: Artery of Percheron, Hyperhomocysteinemia, Ischemic stroke
