Abstract:
Objective To investigate the MRI manifestations and diagnostic value of adenomatoid tumor (AT)of epididymis. Methods The MRI features of 5 patients with AT of epididymis were analyzed retrospectively,which were confirmed by histopathology,and some relevant medical literatures were reviewed.Results The epididymal tumor was manifested as moderate signal on T1 WI and T2 WI,similar to adjacent testicule,and as moderate signal with slightly high rim-enhancement on enhanced T1 WI in 4 cases.Secondary infarction and chronic granulomatous inflammation in 1 patient was found and presented unevenly moderate signal on T1 WI,slight hypointensity on T2 WI, hyperintensity on DWI and rim-enhancement on dynamic enhancement MRI.Few hydrocele was detected in all 5 patients.Conclusion AT of epididymis is a rare benign neoplasm with some characteristic MRI features which is helpful for the preoperative diagnosis.
