Abstract The artery of Percheron (AOP) is a normal variant that supplies the thalamus. AOP infarcts may originate a spectrum of unusual clinical presentations. The diagnosis is difficult due to the lack of sensitivity of detection by CT scan and to the lack of acknowledgment of this clinical entity. We describe the case of a patient who presented with unresponsiveness due to an AOP infarct. Our report serves as a reminder to consider AOP infarct as differential diagnosis when assessing patients with unspecific neurological deficits of unclear origin. Further we reinforce the claim for a low threshold for MRI in patients presenting acutely with otherwise unexplainable neurological symptoms to facilitate diagnosis and decrease patient morbidity.
