卵巢囊腺瘤与囊腺癌的CT诊断

The CT Diagnosis of Ovarian Cystadenoma and Cystadenocarcinoma

目的探讨CT在卵巢囊腺瘤和囊腺癌中的诊断价值。资料与方法回顾性复习经手术和病理证实的13例卵巢囊性肿瘤,总结其CT表现和特征。结果13例中浆液性囊腺瘤7例,黏液性囊腺瘤4例;浆液性乳头状囊腺癌1例(Ⅱa型),黏液性囊腺癌1例(Ⅱb型)。囊腺瘤表现为薄壁的单房或多房囊肿,无壁结节;囊腺癌表现为不规则厚壁,间隔增厚,并有壁结节,软组织成分多。术前CT诊断正确11例(84.6%),误诊2例(15.4%)。结论CT能很好显示卵巢囊腺瘤、囊腺癌的特征,在鉴别良、恶性卵巢囊腺性肿瘤上有价值。

Objective To discuss the CT diagnostic value in the cystadenoma and cystadenocarcinoma of the ovary. Materials and Methods CT features of 13 cases with histologically proven epithelial tumors of the ovary were retrospectively reviewed. Resuits 7 cases were serous cystadenoma, 4 cases were mucinous cystaenoma, 2 cases were cystadenocarcinoma and papillary cystadenocarcinoma, respectively. The CT findings of cystadenoma were thin wall with uniocular or multicular, lacks of the mural nodule. The cystadenocarcinoma findings were thick, irregular wall with thick septa, mural nodule, and soft tissue component. The CT diagnosis were made correctly in 11 cases （84.6%） ; misdiagnosis in 2 cases （ 15.4 % ）. Conclusion CT is a useful technique and has an important clinical vlaue in diagnosis and differential diagnosis of ovarian cystadenuma and cystadenocarcinoma.
