Objective: To investigate MRI manifestations of adenomatoid tumor and its diagnostic value. Methods: Eleven cases of adenomatoid tumor proved by pathology were retrospectively reviewed. Their MRI appearance and signal intensity were analysed correlative literatures. Results: In all 11 cases, 12 foci were found. Eleven foci were found in thesubserous layer and 1 focus was in the myometrium. Eleven solid foci showed slightly low signal intensity or intermediate signal intensity on T1WI, slightly low signal intensity on T2WI and intermediate signal intensity on DWI. Compared to myometrium, the lesions were enhanced after Gd-DTPA injection. The other solid-cystic focus showed mixed signal intensity on T1WI and T2WI with fluid-fluid level. The signal intensity was intermediate on DWI and the solid part was obviously enhanced after Gd-DTPA injection. Conclusion: There are varied MRI manifestations for adenomatoid tumor. Its characteristic features include fluid-fluid level on T1WI and T2WI with clear and obviously enhanced focus compared to myometrium.
