Abstract Objective: To discuss the CT and MR imaging features of metanephric adenoma(MA). Methods: The imaging data of 11 cases of MA confirmed by postoperative special pathology were retrospectively analyzed. Assessed image features including size, shape, density or signal intensity and enhancement style. Results: There were 11 cases of MA, the male to female ratio of cases was 3∶8. All were single masses, including 6 cases in the right kidney and 5 cases in the left kidney. The shape of MA was round. 8 cases were solid and 3 case was cystic solid masses(while 1 case of them presented as mainly cystic mass). On plain CT scanning, the solid component of the masses showed equal or slightly high density. After contrast, the mass was well-defined and the solid part of the mass showed mild to moderate delayed enhancement. MRI examination was performed in 2 cases. The signal intensity in 1 case was similar to the renal parenchyma, while the other one had heterogenous signal intensity with slight long T1 and slight long T2 signal. 2 cases showed the hyperintensity on DWI. Conclusion: Imaging manifestations of MA showed certain characteristic. CT and MRI were valuable in the diagnosis and differential diagnosis.
