Abstract: Objective To evaluate the charateristics of CT and MR imaging of struma ovarii(SO).Methods 10 lesions of 10 pa-tients confirmed by pathology were analyzed retrospectively.6 cases were performed plain and enhanced CT scan and 4 were under-went MR before operation.Imaging features were analyzed retrospectively correlated with histological findings.Results All the SO tumors were appeared as solitary,well-defined,lobulated or oval masses.The largest diameter was less than 10 cm.Ascites were found in 4 cases.Six of SOs were solid-cystic and four were cystic.The cystic portion was low density or high density on CT images. High density cysts were shoewed in 4 cases.On MR images,the cystic portion was hypointenstiy on T1 WI and hypo/hyperintensity on T2 WI.Vacuum phenomenon (hypointenstiy on T1 WI and extremly hypointensity on T2 WI)was observed in 1 case.Solid compo-nent and cystic wall showed remarkable enhancement.Conclusion CT and MR images of SO can reflect its histopathologic charater-istics,which provides important value in the diagnosis and differential diagnosis of SO.
