Cushing's disease is a serious endocrinopathy that, if left untreated, is associated with significant morbidity and mortality rates. After diagnostic confirmation of Cushing's disease has been made, transsphenoidal adenomectomy is the treatment of choice. When a transsphenoidal adenomectomy is performed at experienced transsphenoidal surgery centers, long-term remission rates average 80% overall, surgical morbidity is low, and the mortality rate is typically less than 1%. In patients with well-defined noninvasive microadenomas, the long-term remission rate averages 90%. For patients in whom primary surgery fails, treatment options such as bilateral adrenalectomy, stereotactic radiotherapy or radiosurgery, total hypophysectomy, or adrenolytic medical therapy need to be carefully considered, ideally in a multidisciplinary setting. The management of Nelson's Syndrome often requires both transsphenoidal surgery and radio-therapy to gain disease control.
