[Hypophyseal adenomas: functional and tumor evaluation and therapeutic approaches].

Patients with pituitary adenomas present with hypersecretion syndrome(s), and/or pituitary failure(s), and/or signs of mass effect, or incidentally. Pituitary function evaluation, visual acuity and field check-up, and MRI or at least CAT are compulsory for diagnosis, and for therapeutic approach; surgery for Cushing's disease, dopamine agonists for prolactinomas, somatostatin analogs or surgery for thyrotroph adenomas, surgery and/or somatostatin analogs and/or radiotherapy in acromegaly, surgery with additional irradiation in most adenomas of other types, or even expectation in some instances.
