A case of rare stroke syndrome admitted in intensive care unit - Artery of Percheron infarction

Abstract

Artery of Percheron is a rare anatomical variant of thalamic vascular supply. Stroke involving this vasculature is an uncommon event. Occlusion of this vessel produces a peculiar pattern in the form of bilateral thalamic infarcts with or without midbrain infarction. This results in variable clinical features ranging from somnolence or altered sensorium to coma in affected individuals, accompanied by characteristic neurological manifestations. Diagnosis of artery of Percheron infarction at the initial presentation may be difficult as it is infrequent and early neuroimaging studies may be negative. Here we report a patient, a case of AOP infarct whose MRI brain and clinical picture demonstrated the characteristic features.
