Abstract

Objective To explore the CT and MRI features of pure ovarian dysgerminoma and metastases. Methods 15 cases of pure ovarian dysgerminoma proven pathologically were retrospectively analyzed. Results 13 cases of primary tumor were unilateral,12 cases(12/13) showed lobulated with clear boundary,in 11 cases(11/12),the enhancement of blood vessel was found in the inner and the edge of the tumor, in all cases with ascites,but no peritoneal metastasis,1 case(1/13)with mild enlarge lymph nodes. 4 of the 3 patients with metastatic lesions were similar to the primary tumor in the form and strengthening mode,with multiple enlarged lymph nodes and ascites,and 1 cases(1/3) had peritoneal metastasis. Conclusion CT and MRI performance of pure ovarian dysgerminoma and metastases have certain characteristics，especially enhancement pattern is correlated with pathologic characteristics.CT and MRI each has advantages, combinined with the patient's age and serum LDH,most patients can be correctely diagnosed before surgery.
