Surgical and radiosurgical treatment strategies for Cushing's disease.

Transsphenoidal resection of ACTH producing pituitary adenoma is a safe and highly effective procedure for CD in experienced hands. Radiosurgery is more frequently used as treatment of residual and recurrent adenoma and persistent CD. Long-term endocrine and imaging follow-up is important as delayed recurrences and hypopituitarism are not infrequent.
