卵巢肿瘤的CT诊断（附30例分析）

CT Diagnosis of Ovarian Tumors :An Analysis of 30 Cases

目的：探讨卵巢肿瘤的ＣＴ表现及诊断价值。材料与方法：回顾性分析经手术病理证实的３０例卵巢肿瘤的ＣＴ表现，对照术前Ｂ超结果，探讨卵巢肿瘤的ＣＴ表现，评价ＣＴ对卵巢肿瘤的诊断价值及限度。结果：ＣＴ对卵巢肿瘤的发现率为９７．２２％，对良性肿瘤诊断正确率为８８．８８％，恶性肿瘤为６６．６６％。结论：对多数卵巢病变，如畸胎瘤、囊腺瘤、囊腺癌和部分囊肿有典型的ＣＴ表现，可做出准确诊断；少数卵巢病变，如纤维瘤、转移瘤、交界性肿瘤和良性肿瘤小区恶变，缺乏典型表现。

bjective: To inquire into the feature and diagnosis value of CT scanning in ovarian tumors. Materials and Methods: The CT appearance of 30 cases of ovarian tumors confirmed by biopsy were analysed, the accuracy of CT diagnosis was compared with that of ultrasound examination. Inquire into feature and diagnostic value and limit of CT scanning in ovarian tumors.Results: The finding rate for ovarian tumors by CT was 97.22%, and the accurate rate for benign tumors was 88.88%, for malignant tumors was 66.66%. Conclusion: The diagnosis of most ovarian tumors, such as te ratoma, cystadenoma, cystadenocarcinoma and cyst, could be made by CT based on typical findings. In fibroma. metastatic carcinoma, tumors of borderline malignancy and benign tumors with local malignant change. the characteristic CT appearance was absent, the specific diagnosis thereby could be difficult by CT alone.
