Abstract: Objective To study the CT and MRI features of benign ovarian cystic lesions (BOCL) and to improve the understanding of imaging features.Methods CT and MRI findings were retrospectively reviewed and analyzed in 48 patients with BOCL proved by surgical pathology.CT scan was performed in 35 cases, among which 20 cases were performed with CT enhancement scan;MRI scan was performed in 8 cases, among which 3 cases were performed with MRI enhancement scan and diffusion weighted imaging(DWI).Five cases were performed with both CT and MRI.Results There were 11 cysts (3 simple cysts, 3 corpus luteum cyst, and 5 endometriotic cyst), 10 serous cystadenomas with 13 lesions, 8 mucinous cystadenomas, 9 teratomas with 10 lesions, and 10 struma ovarii.The CT and MRI characteristics of the lesions in size, shape,thickness of cyst wall,wall nodule,density or signal intensity,and enhancement features were helpful in differential diagnosis of BOCL.Conclusion CT and MRI findings of BOCL have certain characteristics, which is significant in the diagnosis, preoperative evaluation and prognosis.
