One of the atypical and unusual presentations of ischemic stroke is an occlusion of the “artery of Percheron” (AOP) which leads to infarction of thalami and mesencephalon. AOP is a rare variant vessel, and its acute occlusion can cause a bilateral symmetrical thalamic stroke. Vertical gaze palsy, memory loss, disorientation, sleepiness, hypersomnolence, or comas are the usual symptoms of bilateral paramedian thalamic infarcts caused by the obstruction of AOP. There are several variants of thalamic blood supply, identifying the potential presence and infarction of an AOP is crucial for diagnosis and treatment of ischemic strokes affecting the thalami and mesencephalon, especially because of the unusual and variable presentation of these forms of ischemic strokes. We describe a case of a 61-year-old man who was otherwise healthy and experienced abrupt onset giddiness followed by loss of consciousness and was later identified with an AOP infarct.
