Objective:To investigate the magnetic resonance imaging (MRI) features of ovarian masses during pregnancy and to evaluate the diagnostic value of MRI in differential diagnosis of ovarian tumors during pregnancy. Materials and Methods:MRI data of 42 pregnant patients with ovarian masses confirmed by surgery and pathology were retrospectively ana-lyzed. The location,morphology,size,texture and signal intensity of the lesions were observed and compared with pathological data. Results:A total of 48 cases of ovarian masses were found in 42 pregnant women,including 36 unilateral and 6 bilat-eral masses with diameter of 3.1～20 cm(mean (9.9±4.3) cm). There were 25 cases(52.0％) of pure cystic masses,8 cases(16.7％) of mainly cystic masses with mural nodules,8 cases(16.7％) of cystic-solid masses and 7 cases(14.6％) solid masses. The his-tological types included 4 cases of malignant tumor(8.3％,namely dysgerminoma,mixed germ cell tumor,mucinous adenocarci-noma and mixed adenocarcinoma). Five cases of borderline tumor (10.4％,3 serous and 2 mucinous tumors). Thirty-nine cases of benign lesions (81.3％) including 4 fibromas,10 cystadenomas (3 serous,7 mucinous),7 mature teratomas,12 ovarian en-dometriotic cysts,2 bilateral ovarian luteinized follicular cysts,2 uterine fibroids and 2 adnexal torsion. Conclusion:Benign cystic tumor is the dominant ovarian mass during pregnancy,while solid components,mural nodules or cystic solid masses in-dicate borderline or malignant tumors. MRI is helpful for the differential diagnosis of ovarian masses during pregnancy.
