卵巢囊腺瘤与囊腺癌的CT征象分析

CT signs analysis on ovarian cystadenoma and cystadenocarcinoma

目的:观察卵巢囊腺瘤与囊腺癌的CT征象,并结合相关文献进行分析,旨在提高CT诊断的正确率。方法:回顾性分析28例手术并经病理证实的卵巢囊性占位患者的病例资料,总结其CT表现和特征。结果:28例中良性13例,其中浆液性囊腺瘤7例,黏液性囊腺瘤5例,浆液性并黏液性囊腺瘤1例,囊腺瘤表现为薄壁的单房或多房囊性肿物,囊液密度均匀,无壁结节;交界性6例,浆液性及黏液性各3例;囊腺癌9例,其中浆液性囊腺癌7例,黏液性囊腺癌2例,表现为囊壁和间隔的不均匀增厚,出现壁结节及实性团块,周围浸润及腹膜转移,腹腔积液形成。结论:单房浆液性囊腺瘤及多房黏液性囊腺瘤具有典型CT表现,CT易于诊断,当病变出现囊壁分隔不规则增厚或壁结节时,提示交界性或恶性变。CT能显示卵巢囊腺瘤及囊腺癌的特征,可为临床提供手术和治疗方案的依据。

Objective：To observe and analyze the CT signs of ovarian cystadenoma and cystadenocarcinoma ac- cording to related literature ,to improve the accuracy of CT diagnosis. Methods ：To analyze the clinical data of 28 cases with ovarian cystadenoma and cystadenocarcinoma proved by surgery and pathology retrospectively. Results：Of 28 cases, 13 cases were benign, 7 cases were serous cystadenoma, 5 cases were mucinous cystadenoma, 1 cases were serous and mucinous cystadenoma. The CT findings of cystadenoma thin wall with uniovular or multicular,liquid den- sity,lacks of the mural nodule. 6 cases were borderline, serous and mucinous each 3 cases. 9 cases were cystadenocar- cinoma. 7 cases were serous,2 cases were mucinous. The cystadenocarcinoma findings were thick,irregular wall with thick septa,mural nodule,and soft tissue component,the surrounding tissue infiltration and peritoneal metastatic. Conclusions ..Unilocular and multilocular serous cystadenomas has typical CT signs for diagnosis. It is difficult to iden- tify borderline cystadenoma. When cystic and solid area or protruding wall nodes ,irregular thick wall and septa appear in the tumor ,it usually suggests that borderline or malignant transformation exists.
