摘要
目的 :探讨卵巢上皮癌的CT诊断价值。方法 :对经手术病理证实的卵巢上皮癌20例共29个肿瘤的CT表现进行回顾性分析。结果 :①CT对卵巢肿瘤的检出率为96 7% ,定性诊断准确率90 % ;②卵巢上皮癌在CT影像上表现为盆腔内不规则形肿块 ,依肿瘤密度不同分为实性、囊性和混合性3种 ,以混合性最多见占79 3 % ;③CT对右膈下大于或等于5mm转移灶敏感性为100 % ,对大网膜及子宫直肠窝大于5mm转移灶敏感性分别为85 7%和62 5% ,对大于1cm转移淋巴结的敏感性为66 7%。结论
Objective:To discuss the value of CT diagnosis of the ovarian carcinomas.Methods:The CT findings of 20 cases of ovarian carcinomas confirmed by surgery and pathology were analysed retrospectively.Results:①CT has a detection rate of 96 7% for ovarian tumors and an accuracy rate of 90% in qualitative diagnosis.②ovarian epithelioma present irregular masses in pelvic in CT.The masses can be divided into solid,cystic and mixed types.③CT has a sensitivity of 100% for a right subdiaphragmatic metastasis focus of 5mm or more.It has relatively a sensitivity of 62 5% and 85% for metastasis focus of 5mm or more in rectouterine pouch and omentum majus while a sensitivity of 66 7% for metastasis lymph node over 1cm.Conclusion:CT is valuable for the qualitative diagnosis of ovarian epithelioma and the detecting metastasis focus in abdomen.
