目的探讨腹部异位嗜铬细胞瘤的影像特征。方法结合文献对9例腹部异位嗜铬细胞瘤的影像表现进行描述与分析。结果9例异位嗜铬细胞瘤均异位于腹膜后，其中既有双侧肾上腺原发灶又有异位于腹主动脉旁的1例。瘤体多大于3cm，有完整或部分的包膜及壁，病变边缘多呈不规则形或分叶状，其内坏死囊变多见而钙化少见，增强后均有明显或较明显环状强化内部或呈多房性强化。结论根据CT及MRI改变和典型的临床表现可对异位嗜铬细胞瘤可作出比较正确的定位、定性诊断。

Objective To investigate the imaging features of abdominal ectopic pheochromocytoma. Methods To describe and analyze the features of 9 cases of abdominal ectopic pheochromocytoma image. Results 9 cases of ectopic pheochromocytoma were different in the peritoneum in which there were bilateral adrenal primary tumors and 1 case was ectopic in abdominal aorta. The tumor is larger than 3cm with full or partial capsule and wall. The edge of the lesion is more irregular or lobulated with more cystic necrosis but rare calcification. After enhancement an annular strengthening internal was obvious or it showed a multilocular enhancement. Conclusion More accurate positioning and qualitative diagnosis can be made according to CT and MRI changes and typical clinical manifestation of ectopic pheochromocytoma .
