초록
Adrenal medullary hyperplasia is an increase in the mass of the adrenal medullary cells. We report a case of a 38-year-old man presenting with pheochromocytoma-like symptoms who was preoperatively misdiagnosed with pheochromocytoma. Hypertension was associated with an intracranial hemorrhage evident in a brain computed tomography scan, in which no obvious pituitary gland enlargement was detected. An abdominopelvic CT revealed a solitary tumor in the right adrenal gland with no obvious enlargement of the contralateral adrenal gland or sympathetic chains. Lab results showed increased levels of urinary metanephrines. Based on clinical data, the patient underwent a laparoscopic right adrenalectomy bases on a diagnosis of pheochromocytoma. The patient was finally diagnosed with adrenal medullary hyperplasia with coexisting ipsilateral non-functioning adrenal cortical adenoma. Postoperatively, blood pressure and lab results were maintained in the normal range and the patient was symptomatically free during the follow-up period. (Korean J Endocrine Surg 2011;11: 182-185)
Abstract
Adrenal medullary hyperplasia is an increase in the mass of the adrenal medullary cells. We report a case of a 38-year-old man presenting with pheochromocytoma-like symptoms who was preoperatively misdiagnosed with pheochromocytoma. Hypertension was associated with an intracranial hemorrhage evident in a brain computed tomography scan, in which no obvious pituitary gland enlargement was detected. An abdominopelvic CT revealed a solitary tumor in the right adrenal gland with no obvious enlargement of the contralateral adrenal gland or sympathetic chains. Lab results showed increased levels of urinary metanephrines. Based on clinical data, the patient underwent a laparoscopic right adrenalectomy bases on a diagnosis of pheochromocytoma. The patient was finally diagnosed with adrenal medullary hyperplasia with coexisting ipsilateral non-functioning adrenal cortical adenoma. Postoperatively, blood pressure and lab results were maintained in the normal range and the patient was symptomatically free during the follow-up period. (Korean J Endocrine Surg 2011;11: 182-185)
