[Bilateral laparoscopic adrenalectomy in ACTH-independent macronodular adrenal hyperplasia: a case report]

We report a case of ACTH-independent macronodular adrenal hyperplasia (AIMAH). A 62-year-old man was admitted to our hospital for further examination of obesity and diabetes mellitus. He was diagnosed with Cushing's syndrome by endocrinological examinations, and computed tomography and magnetic resonance imaging findings revealed nodular hyperplasia in bilateral adrenal glands, suggesting its etiology to be AIMAH. We underwent simultaneous bilateral laparoscopic adrenalectomy. A preoperative diagnosis of AIMAH was confirmed by histological examination of both adrenal glands, weighing 21 g (right) and 16 g (left). The postoperative course was uneventful. We believe that simultaneous bilateral laparoscopic adrenalectomy is feasible, safe, and results in minimal postoperative morbidity for the treatment of AIMAH.
