Acute bilateral paramedian thalamic and rostral midbrain infarction due to occlusion of artery of Percheron

Abstract

This case highlights a patient presented with unusual symptoms, who was diagnosed on imaging with bilateral thalamic infarcts, probably due to an unusual anatomic variant. These paired lesions have a limited differential diagnosis that includes metabolic and toxic processes, infection, vascular lesions, and neoplasm. These differential diagnoses further narrowed with knowledge of the specific imaging characteristic of the lesions in combination with patient history.

Key-words: differential diagnosis, bilateral thalamic infarction, artery of Percheron.
