Cardioembolic Artery of Percheron Infarction

Abstract

Occlusion of the artery of Percheron (AOP) is a rare yet potentially disabling form of ischemic stroke resulting in infarction of the bilateral paramedian thalami and mesencephalon with variable and often atypical presentation. Given the various patterns of thalamic blood supply, recognizing the presence of AOP infarction is crucial for the diagnosis and management of ischemic strokes involving these regions. Here, we report a case of acute hemorrhagic infarction involving the bilateral thalami and the rostral mesencephalon caused by a cardioembolic occlusion of the AOP.

Keywords: acute cerebral ischemic stroke; artery of percheron infarct; ischemic cerebrovascular disease; posterior circulation stroke; vascular neurology.
