卵巢肿瘤的CT诊断与鉴别诊断

目的：提高卵巢肿瘤CT诊斯的正确性。材料和方法：回顾28例37个经手术病理证实卵巢肿瘤CT资料，分析肿块车身CT特征(囊性，实性，囊实性)，及其伴同变化。讨论良、恶性卵巢肿瘤的定位与定性诊斯。结果：全腹部，大间距，多次的CT检查技术可对较大的卵巢肿瘤与卵巢外肿块作出鉴别。囊性肿块80%为良性，实性肿块87．6%为恶性，而囊实性肿块的良、恶性分别为57.14%与与42．86％。结合肿块外形轮廓、囊实性成分比例、伴发的腹水及邻近脏器变化等CT表现可对本组术前误诊病例及CT表现不典型者作出良、恶性鉴别。结论：CT检查可对卵巢肿瘤的定位及良、恶性作出定性诊断。

The CT Diagnosis and Differential Diagnosis of Ovarian Tumors

Purpose: For promoting the CT diagnostic accuracy of ovarian tumors. Materials and Methods: 37 surgical pathologic proved ovarian tuniors with their CT images in 28 cases were analysed retrospectively including CT specificities of cystic, solid, cystsolid and the related accompanied changes. The localization and cell determination of benign and malignant nature of the ovarian tuniors were also discussed. Results: The multiple times CT scans with different intervals can differentiate rather big ovarian tuniors with extra-ovarian tumors. 80% of cystic masses were proved as benign while 87.5% solid masses as malignant, simultaneously the distribution of benign and malignant percentages among cyst-solid masses were 57.14% and 42.86% respectively. The differential diagnosis of benign and malignant ones in preoperative wrong diagnostic and atypical CT finging cases can be further promoted by analysing the shape contour, the proportion between cyst and solid content of the masses together with CT manifestations ascites and changes of nearby organs. Conclnsion: CT scan can determine the localization, benign, and malignant nature of the ovarian tuniors.
