Abstract:
Objective To explore the MRI features of struma ovarii(SO).Methods The clinical and MRI data of 14 cases of SO confirmed by operation and pathology were collected.The lesions'site,morphology,signal characteristics,and the enhancement mode of different internal components were analyzed,and the MRI features of the lesions were summarized.Results All 14 cases had uni-lateral onset,8 cases on the left side,and 6 cases on the right side.8 cases were cystic-solid,and 6 cases were cystic.11 cases were multilocular and 3 cases were unilocular.MRI signals were mixed(high,equal,and low signals all could appear),11 cases had at least two places of extremely low signal on T2WI in the lesions,and 12 cases had slightly high or high signal on T1WI in the lesions.The diffusion of the lesions was not limited,or the solid component,thicker septation,and cystic wall were limited to different degrees.The solid component,septation,and cystic wall of the lesions were enhanced significantly,but the cystic cavity was not enhanced.Conclusion MRI features of SO:unilateral ovarian multilocular cystic-solid or cystic mass;mixed signals,extremely low signal on T2WI,slightly high or high signal on T1WI;no limitation on the diffusion of the lesion,or solid component,thicker septation and cystic wall are limited to different degrees;the solid component,septation and cystic wall of the lesion are enhanced significantly.
