Differences in clinical, hormonal, and radiological presentation and in surgical outcomes in patients presenting with and without pituitary apoplexy. A multicenter study of 245 cases.

Surgical resection is more common in patients presenting with pituitary apoplexy than those without apoplexy; however, visual improvement and complete recovery of pituitary function is more common in patients without apoplexy. The risk of new pituitary deficits and permanent diabetes insipidus is higher in patients with apoplexy than in those without it.
