[Necrosis of a hypophyseal adenoma and ischemic cerebral vascular accident ].
A 78-year old man developed an acute intracranial hypertension followed by central left facial palsy. CT Scan and MRI revealed an ischemia within the right lenticulostriate arteries territory and a hemorrhagic infarction of a pituitary adenoma without extrinsic carotid artery compression. Neuroophthalmologic examination and hormonal screening were normal. Though pituitary apoplexy and stroke might represent a fortuitous association, several mechanisms underlying such clinical picture are advanced.
