Abstract Introduction Bilateral thalamic infarcts are rare presentations of stroke. They are the result of a complex combination of risk factors and a predisposing vessel distribution. The artery of Percheron characterized by a single arterial trunk that irrigates both paramedian thalamic regions can be occluded as a result of embolic diseases leading to bilateral paramedian thalamic infarcts. Clinical and image findings of this uncommon form of posterior circulation infarct are presented along with their anatomic and pathophysiologic correlates. Case presentation A 27-year-old Mexican man with no relevant medical history was admitted to hospital after he was found deeply stuporous. On admission an urgent neuroimaging protocol for stroke including magnetic resonance imaging and magnetic resonance imaging angiography was performed. The scans revealed symmetric .
