CT DIAGNOSIS OF OVARIAN CYSTADENOCARCINOMA

[Objective]To evaluate CT scan in the diagnosis of ovarian cystadenocarcinoma.[Methods]CT features of 38 cases with histologically proven epithelial tumors of the ovary were analyzed.[Results]CT features of serous cystadenoma took the typical type I form,in which the cystic fluid displayed homogeneous water attenuation.The CT findings of cystabenoma were thin wall with uniocular or multicular,lacks of the mural nodule.The serous cystadenocarcinoma was typically of type Ⅱ.The malignant and benign tumors carried several same CT features.The cystabenocarcinoma findings were thick,irregular wall with thick septa,mural nodule,and soft tissus component.Ovarian neoplasms mainly located at the adnexal area.Type I and type Ⅱ were commonly seen.The benign turmors often presented as type I,while the malignant ones often presented as type Ⅱ.[Conclusion]CT is an useful technique and has an important clinical vlaue in the diagnosis and differential diagnosis of ovarian cystadenoma and sytadenocarcinoma.
