目的：探讨卵巢子宫内膜样癌的MRI特征，以提高对该病的认识。方法回顾性分析14例经手术病理证实的卵巢子宫内膜样癌的MRI表现，并与术后病理结果及分期进行比较。结果14例子宫内膜样癌患者中，术前MRI均诊断为恶性肿瘤，正确率100％，诊断为子宫内膜癌仅3例，正确率仅21％；MRI术前分期：Ⅰ期2例，Ⅱ期6例，Ⅲ期5，Ⅳ期1例，术后病理分期：Ⅰ期3例，Ⅱ期4例，Ⅲ期6例，Ⅳ期1例，MRI分期的准确性85．7％。结论 MRI对卵巢子宫内膜样癌术前良恶性判断上具有较高准确性，其分期与手术病理分期具有良好的一致性，但术前明确定性子宫内膜样癌的准确率不高。%Objective To investigate the MRI characteristic findings of ovarian endometrioid carcinoma ( OEC) so as to ele-vate the understanding of OEC .Methods MRI manifestations in 14 patients with ovarian endometrioid carcinomas confirmed by surgery and pathology were analyzed retrospectively and were compared with the post -operative pathological findings and stages . Results In the 14 patients with endometrioid carcinomas , all were diagnosed as malignant tumor by MRI preoperatively , with the accuracy of 100%;3 cases were diagnosed as endometrial carcinoma , with the the accuracy of only 21%.Preoperative MRI stag-ing were that there were 2 cases in stage Ⅰ, 6 cases in stageⅡ, 5 cases in stage Ⅲ stage, 1 case in stage Ⅳ.Post-operative pathological stagings were that there were 3 cases in stageⅠ, 4 cases in stageⅡ, 6 cases in stageⅢ, and1 case in stageⅣpe-riod in.MRI staging accuracy was 85.7%.Conclusion MRI has higher accuracy for the preoperative judgment for the benign and malignancy of OEC , which has good consistency with pathology and surgery staging .However , the preoperative accuracy for clearly determining endometrial carcinoma is relatively lower .
