Background: Bilateral adrenal tumors are not common in clinical practice, but are an important source of ectopic adrenocorticotropic hormone (ACTH) secretion. Standard operative management for bilateral pheochromocytomas might dictate the removal of the involved adrenal gland and the removal of the contralateral adrenal gland. We present a case of bilateral ACTH-secreting pheochromocytoma treated with staged laparoscopic unilateral total and contralateral subtotal adrenalectomy. Case Presentation: A 58-year-old male with elevated hyperglycemia and general fatigue was hospitalized for pneumonia. CT incidentally revealed bilateral adrenal tumor. Biochemical examination was significant for elevated urinary metanephrine and normetanephrines, and plasma catecholamine level. CT scan of the head, neck, thorax, and pelvis was normal. Under the clinical diagnosis of ACTH-dependent pheochromocytoma, laparoscopic right total adrenalectomy was performed. As endocrinologic examination showed residual ACTH-dependent pheochromocytoma after surgery, laparoscopic left subtotal adrenalectomy was performed. Pathology analysis revealed pheochromocytoma with stained ACTH lesions in both adrenal tumors. Conclusion: This is a rare case of ACTH-secreting bilateral pheochromocytoma effectively treated with staged laparoscopic unilateral total and contralateral subtotal adrenalectomy, in which the production of ACTH was confirmed by immunohistochemical staining.
