摘　　要：目的探讨卵巢单纯型无性细胞瘤及转移瘤的CT、MRI特点。方法回顾性分析15例经手术病理证实的单纯型无性细胞瘤的CT、MRI表现。结果 13例原发肿瘤均单发,12例(12/13)呈分叶状,边界清晰,11例(11/12)肿块内及边缘见强化血管影,所有病例均伴腹水,但无腹膜转移,1例(1/13)伴轻度肿大淋巴结。3例4个转移瘤的形态及强化方式与原发灶相近,均伴多发肿大淋巴结及腹水,1例(1/3)有腹膜转移。结论卵巢无性细胞瘤原发灶及转移瘤的CT、MRI表现有一定特征性,尤其是强化特征能够反映其病理特点,CT、MRI检查各有优势,结合患者的年龄及血清LDH,大多数可术前正确诊断。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. Restdlts 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. Condusiota 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.
