The Percheron artery is a rare thalamic vasculature variant and is a single dominant thalamoperforating artery supplying bilateral paramedian thalamic territories. Occlusion of the aretery of Percheron results in a characteristic pattern of bilateral paramedian thalamic infarcts and is estimated to represent between 0.1%-0.3% of all ischemic strokes and 4% to 35% of all thalamic strokes. Despite our knowledge of the characteristic radiologic features of an aretery of percheron stroke, the true incidence of aretery of percheron strokes is challenging to estimate due to nonspecific clinical symptoms and subtle findings on computed tomography (CT) and magnetic resonance imaging (MRI). We report a case series of three patients with aretery of percheron stroke confirmed by radiologic imaging.
