title: Bilateral thalamic infarctions due to occlusion of artery of Percheron.
abstract: The artery of Percheron is an uncommon anatomic variant in which a solitary trunk originates from either posterior cerebral artery and provides arterial supply to bilateral paramedian thalami and the rostral midbrain (Fig. 1). Recognition of this anatomical variant is essential in establishing the stroke mechanism in bilateral paramedian thalamic infarcts. We describe the clinical presentation and neuroimaging characteristics in a patient with bilateral thalamic infarctions due to occlusion of the artery of Percheron.
