摘要
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 elevate 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 staging were that there were 2 cases in stage Ⅰ , 6 cases in stage Ⅱ, 5 cases in stage Ⅲ stage, 1 case in stage Ⅳ. Post-operative pathological stagings were that there were 3 cases in stage Ⅰ , 4 cases in stage Ⅱ , 6 cases in stage Ⅲ, andl case in stage Ⅳ period 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.
