摘　　要：Background Adrenal ganglioneuroma is a rare adrenal pathogenic disease with difficult differential diagnosis from adrenal pheochromocytoma. Currently, very limited literature is available to allow a differential diagnosis of these two conditions from each other. This study aimed to evaluate the clinical profile, differential diagnosis and surgical treatments of both conditions. Methods Clinical characteristics of 36 patients with adrenal pheocheomocytoma and 18 patients with adrenal ganglioneuroma were analyzed. Data from CT scans and surgical treatments from 1999 to 2007 were collected. Endocrine hormone tests and ^131I-metaiodobenzylguanidine （MIBG） were performed. Neither ^131I-MIBG nor endocrine hormone tests were available in 9 cases of asymptomatic adrenal ganglioneuroma with tumor size less than 4 cm and there were negative findings from contrast enhanced CT scans. The level of urine catecholamine of patients was compared by one-way analysis of variance. Results The mean age of patients in the adrenal ganglioneuroma group was 41.2 years （16-67 year） and in the adrenal pheochromocytoma patients 38 years （17-74 year）. Contrast enhanced CT showed that the foci were intensified in 5 cases （27.8%） of adrenal ganglioneuroma and there were obvious contrast indications in 30 （83.3%） of the pheochromocytoma. Catecholamine levels in a 24-hour urine sample were normal in 4 patients with adrenal ganglioneuroma and increased in 36 （100%） cases with adrenal pheochromocytoma. ^131I-MIBG nuclear scan showed negative results in 4 patients （100%） with adrenal ganglioneuroma and positive results in 25 （96.2%） with adrenal pheochromocytom. Laparoscopy for adrenal tumors was performed through a transperitoneal or retroperitoneal approach during a follow-up period of （43±6） months, and all cases survived well. Conclusions CT, urinary catecholamine and ^131I-MIBG are standard and efficient tools for differential diagnosis of adrenal ganglioneuroma from pheochromocytoma.
