[Cushing's syndrome caused by a bilateral adrenal adenoma (author's transl)].

An unusual of bilateral adrenal benign adenoma with Cushing's syndrome is reported. Nine months after bilateral adrenalectomy, no more sign of hyperadrenocorticism was present. An adenoma was found in each gland with adjacent tissue atrophic. Physiopathology is not clear even if suppression test by dexamethasone and stimulation test by lysin-vasopressin are compatible with a central origin.
