Artery of Percheron infarct with multiple cranial nerve palsies and Horner Syndrome

The artery of Percheron is a rare variant of posterior cerebral circulation that supplies both paramedian thalamic zones in addition to variably supplying the midbrain. Overall, this case highlights the importance of considering rare anatomical variants when working up ophthalmic deficits in a stroke patient. Early diagnosis can lead to adequate therapy and prevent complications in the future.
