Abstract:
Objective To improve the diagnostic accuracy by analyzing the CT manifestations of ovarian cystadenoma .Methods The CT images of 57 patients with 62 ovarian cystadenomas proved by surgery and pathology were studied retrospectively . Results Of 62 ovarian cystadenomas, 26 cases with 31 tumors were serous,another 31 cases were mucinous . Unilocular and multilocular forms were seen respectively in 19(61.3%)and 12(38.7% ) of 31 serous cystadenomas, and in 3(9.7%)and 28(90.3%) of 31 mucinous cystadenomas.22 (71.0%) tumors were benign, and 9(29.0%)were of borderline and/or malignant transformation in 31 serous cystadenomas.23 (74.2%) tumors were benign, and 8 (25.8%) were of borderline and/or malignant transformation in 31 cases of mucinous cystadenomas.Benign cystadenomas were frequently round or oval cysts with thin regular wall and septa.Borderline or malignant transformation cystadenomas demonstrated predominately thick irregular wall or septa with projections.The overall preoperative accuracy of characterization was 48.4% in serous and 77.4% in mucinous cystadenomas.Conclusion Multilocular cystadenomas have the typical CT manifestations and CT is a high valuable procedure for imaging them, whereas unilocular cystadenomas, having similar CT findings with some other benign cystic lesions, are lack of enough characteristic features for CT correct characterization.
