Abstract:
The thalamic vascular supply is categorized into the anterior, paramedian, inferolateral, and posterior territories. The artery of Percheron (AOP), a solitary trunk that is an uncommon anatomic variant, provides bilateral arterial supply to the paramedian thalami and the rostral midbrain. Occlusion of this artery results in bilateral thalamic and mesencephalic infarctions. The case described herein is of a patient with AOP who presented with the sudden onset of lethargy.
