摘　　要：目的:探讨CT、MRI检查对异位嗜铬细胞瘤的诊断价值和检查方案。方法:回顾性分析有完整病史资料及手术病理结果的17例病例,其中CT检查15例,MRI检查10例。良性12例,恶性5例。结果:异位嗜铬细胞瘤发病率远远超过10%,并呈轻度青少年及男性成年优势分布,恶性比率达29.4%。CT诊断正确率为86.7%,MRI诊断正确率为100%。搜索性平扫、增强扫描和临床资料对诊断起关键作用。结论:CT、MRI是异位嗜铬细胞瘤定位定性诊断中有效的影像学方法,并能对良恶性肿瘤作出较准确的判断。Objective： To investigate the value of CT and MRI in diagnosing ectopic pheochromoeytoma and the CT and MRI examination protocols.Methods：CT scan was performed in 15 patients and MRI were performed in 10 patients. CT and MRI findings of 17 eases （ 18 lesions） with pathologically-proved ectopic pheochromoeytoma were retrospectively analyzed. Twelve benign and five malignant lesions were included in this study. Results：The incidence of ectopic pheoehromoeytoma was much higher than 10% as reported in the past literatttre. The ectopic pheochromoeytoma seemed to have a predilection for adolescents and men. The incidence of malignant ectopic pheochromocytoma was rather high reaching 29.4%. The accuracy of CT diagnosis was 86.7% and MRI was 100% in this series. The clinical information, plain scan for screening and enhanced scan were very useful for accurate diagnosis. Condusion：CT and MRI are effective imaging medality in diagnosis ectopic pheochromoeytoma in localization and determination of the pathologic natttre, and they can reach a high accuracy in differentiating benign and malignancy.
