Embolic infarct presented with bilateral thalamic lesions possibly initiated by an emboli to the artery of Percheron.

Bilateral thalamic infarcts are rare and present with varying symptoms. Cardioembolism and small artery disease are the most common etiologic factors. The occlusion of a rare arterial variant called the artery of Percheron results in bilateral thalamic infarcts. Herein, we present the imaging findings of an embolic infarct starting from bilateral thalami, probably due to an emboli to the artery of Percheron first.
