Methods :CT scan was performed in 15 patients and MRI were performed in 10 patients. CT and MRI findings of 17 cases ( ) 18 lesions with pathologicallyproved ectopic pheochromocytoma were retrospectively analyzed. Twelve benign and five malignant lesions were included in this study. Results :The incidence of ectopic pheochromocytoma was much higher than 10 % as reported in the past liter ature. The ectopic pheochromocytoma 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.Conclusion :CT and MRI are ef fective imaging modality in diagnosis ectopic pheochromocytoma in localization and determination of the pathologic nature , and t
