CT Features of Peritoneal Metastasis / 中国普外基础与临床杂志

ABSTRACT

Objective To study the CT features of peritoneal Metastasis in post-operative patients of ovarian carcinomas.Methods CT appearance of peritoneal metastasis of ovarian carcinomas proved by surgery and pathology in 33 post-operative patients were reviewed.The CT features of the foci were recorded and analyzed,especially on the location,quantity,density and size.Results In the peritoneal cavity,186 implant foci and 10 recurrent foci were found.metastasis often occurred in the right upper abdomen,especially the right subphrenic spaces.The most frequent locations were the right suprahepatic and subhepatic spaces,the small bowel mesentery,the gastrocolic ligament and the omentum.The density of the foci was most of solid.The size was ranged from 0.5~13 cm.Conclusion Peritoneal metastasis is the most frequent route of metastases for ovarian carcinomas.It is frequently found in upper abdomen,especially in the subphrenic spaces.Localized ascites in the peritoneal cavity is another important sign suggesting peritoneal implants.CT scan from the diaphragm to the pelvic floor will be helpful to diagnose peritoneal implants in cases of post-operative ovarian carcinomas.
