A case of mistaken identity: Giant cystic pheochromocytoma1

Cystic PCCs may not present with the classic prodromal symptoms associated with solid PCCs. This case represents the complex and unsuspected presentation of an extremely rare functional cystic neoplasm. A high index of suspicion for cystic PCC is necessary when confronted with cystic lesions in the vicinity of the adrenal glands. Failure to recognize cystic PCC before resection may lead to uncontrollable hypertension in the operating room, with potentially serious consequences.
