卵巢恶性肿瘤上腹部转移的CT征象

CT Signs of Upper Abdominal Metastases Originated from Ovarian Carcinomas

目的 探讨卵巢恶性肿瘤上腹部转移的CT表现特征。资料与方法 回顾性分析 2 3例经手术及病理证实为原发性卵巢恶性肿瘤 ,CT显示有上腹部转移的表现特征 ,着重观察和分析病变的部位、形态、密度和大小。结果 2 3例中共发现上腹部转移病灶 136个。以腹膜转移为主 (占病灶总数的 72 .8% )。其中最常见于右肝上间隙和右肝下间隙。转移病灶形态以结节团块为主 ,密度以实性为主 ,直径在 0 .5～ 13.0cm之间。结论 卵巢恶性肿瘤上腹部转移十分常见 ,以腹膜转移为主。上腹部CT扫描有助于较全面地发现转移病灶 。

Objective To discuss CT features of upper abdominal metastases originated from ovarian carcinomas. Materials and Methods CT findings in 23 with pathologically proved primary ovarian carcinomas were retrospectively analyzed. The signs of upper abdominal metastases were observed, focusing on the location, morphology, density and size of the lesions.Results A total of 136 upper abdominal metastatic lesions was found, peritoneal metastasis was most commonly seen (99/136, 72.8%), with the right supra-hepatic and infra-hepatic spaces being the most frequent locations. The metastatic lesions were mainly presented as solid nodules or masses ranging in a size of 0.5～13cm. Conclusion Metastasis of ovarian carcinoma to upper abdomen is a common clinical finding. The peritoneum is most commonly affected. CT scanning of the upper abdomen is of help in detecting all metastatic lesions, which is important for making a proper management.
