Bilateral paramedian thalamic infarction in the setting of uncontrolled atrial fibrillation with rapid ventricular response

Abstract

This case report outlines the first reported case of bilateral paramedian thalamic infarct, likely stemming from a rare artery of Percheron (AOP) variant, secondary to uncontrolled atrial fibrillation with rapid ventricular response. We underscore the importance of considering hypoperfusion due to decreased cerebral perfusion as a potential mechanism in cryptogenic AOP infarcts, challenging the conventional association with embolic etiology. This report contributes to the limited literature on AOP infarctions, emphasizing the need for heightened awareness among healthcare providers for diverse clinical presentations and potential etiologies to improve diagnosis and management, ultimately enhancing patient outcomes.
