Abstract:
Objective To analyses the CT characteristics of primary malignant ovarian tumors and metastatic ovarian carcinoma and its diagnosis and differential diagnosis.Methods CT findings in 31 patients with pathologically-proved malignant ovarian tumors,encountered during 1999-04~2003-11 were retrospectively analyzed.The observation of the lesion was focused on the following aspects:location,internal density,septa,wall,intra-cystic and extra-cystic vegetation,the composition of the soft tissue,ascites,peritoneum,mental implantation and metastatic lymphadenopathy.The characteristic of each in both primary malignant ovarian tumor and metastatic ovarian tumor were compared.Results Among the 24 primary malignant ovarian tumors,13 patients had lesions in both sides of ovary,type Ⅱa:n=3,Type Ⅱb:n=11,Type Ⅱc:n=7,Type Ⅲ:n=3.Among the metastatic ovarian carcinomas,Type Ⅱa:n=6,Type Ⅱc:n=1.Conclusion Type Ⅱb and Ⅱc are commonly seen in primary malignant ovarian tumors.Type Ⅱa is always seen in metastatic ovarian carcinoma.The metastatic tumors often happen in the right peritoneum,epiploon,and liver."arborization and silk screen likely"are the characteristic representation of the metastatic ovarian carcinoma.
