    【Abstract】 Objective To investigate clinical and CT features of ectopic pheochromocytoma.Methods 15 cases ectopic pheochromocytoma with complete medical records and operation pathology, proved by CT were retrospectively analyzed. Results The rate of tumors found with CT was 100%. In 15 cases, 13 cases were preoperative diagnosed, and the accuracy of CT diagnosis was 86.7%.There were 13 benign and 2 m alignant cases, and the incidence of m alignant ectopic pheochromocytoma was 13.3%. Conclusion CT is the most effective imaging modality in ectopic pheochromocytoma diagnosis, localization and determination of pathologic nature. CT examination coupled with clinical features and imaging characteristics is very meaningful in accurate diagnosis, making operation programs and reducing operation mistakes of ectopic pheochromocytoma. ......
