Pituatry apoplexy is caused by bleeding into the pituitary gland. Most often it occurs in a pituitary adenoma. These adenomas have decreased blood supply and angiogenesis as compared to normal pituitary gland. [1] [2] In addition, these vessels have fenestrated endothelium surrounded by a variable number of smooth muscle cells. which are not found in normal pituitary gland. [3].
