Abstract
The authors present a critical review of the literature on the hemorrhagic complications of pituitary adenomas, especially those leading to apoplexy. They emphasize the distinction between pituitary apoplexy, hemorrhages leading to sudden endocrine alterations, and asymptomatic hemorrhages. Moreover, they speculate upon the possible pathophysiology of pituitary apoplexy and its predisposing factors. The clinical presentation, natural history, radiological findings, and differential diagnosis are also discussed. Finally, the historical evolution of the treatment of pituitary apoplexy is reviewed, with emphasis on the surgical treatment.
