Benign giant adrenal cyst and parathyroid adenoma: a case report.

An unusual case of a benign adrenal cyst and a parathyroid adenoma occurring in a 59-year-old man with hypercalcemia is reported. Excretory urography, ultrasound, renal aortography, computerized axial tomography and selective thyroid venous sampling were used to establish a diagnosis. Left adrenalectomy was done because of a suspicion of malignancy, which was followed by excision of a retrolaryngeal parathyroid adenoma.
