Infarction in Percheron territory is a rare phenomenon, in this opportunity, we present the second report of Artery of Percheron infarction after endoscopic pituitary surgery in a male patient of 52 years old with a pituitary macroadenoma with a review of the anatomy and most frequent complications for trans-sphenoidal approach.
