Pituitary apoplexy is caused by an infarction or a hemorrhage in a pituitary adenoma. It is a very serious but rare accident. We present the case of a 28-year-old patient with no specific history who had experienced severe acute headache and a sudden decrease in visual acuity. Clinical examination showed a VA with negative light perception on the right and 1/10 on the left , bilateral aréflective mydriasis ODG, ocular motility preserved bilaterally, with normal FO in both eyes. An emergency CT scan of the brain reveals a giant intra-sellar pituitary adenoma and a hemorrhagic area in it’s center evoking a picture of pituitary apoplexy.
