The artery of percheron is a rare vascular variant, occlusion of which is uncommon and associated with bilateral paramedian thalamic infarcts with or without mesencephalic infarctions. We report a case of a 50 year-old male patient with acute bilateral thalamic infarcts. Patient presented with history of sudden onset of altered sensorium with episodes of restlessness, agitation and loss of consciousness. Non-contrast CT scan of head was suggestive of bilateral paramedian thalamic infarcts.
