摘　　要：目的:探讨64层螺旋CT对混合性生殖细胞瘤的诊断价值。方法:回顾性分析7例经病理证实的混合性生殖细胞瘤的CT平扫及两期增强表现、病理标本及切片特征。结果:7例病灶3例位于卵巢,3例位于前纵隔,1例位于睾丸;其中3例边界清楚;各病灶密度不均匀,内见囊变、坏死区,1例可见脂肪及钙化;增强扫描静脉期较动脉期强化明显,均呈不均匀强化。病理结果2例卵黄囊瘤与成熟畸胎瘤混合型,2例卵黄囊瘤与未成熟畸胎瘤混合型,1例卵黄囊瘤、胚胎性癌、畸胎瘤混合型,1例绒癌与无性细胞癌混合型,1例精原细胞瘤、胚胎性癌、滋养细胞成分混合型。结论:64层螺旋CT对混合性生殖细胞瘤的诊断虽无特异性,但在一定程度上为肿瘤良恶性判断、临床分期提供十分重要的依据。Objective：To investigate the diagnostic value of mixed germ cell tumor by 64-slice spiral CT.Methods：The plain CT and two-phase enhanced CT scanning and pathological specimens of 7 cases of the tumor confirmed by pathology were retrospectively studied.Results：3 cases were found in ovarian and 3 cases in anterior mediastinum and 1 case in testis.3 lesions were clear boundary,with fat and calcification in 1 lesion.All the lesions were uneven density and the cystic or necrotic area could be found.Venous phase enhancement was significantly higher than other phase,showed inhomogeneous enhance.Pathological findings： induded 2 cases of yolk sac tumor and mature teratoma mixed,2 cases of yolk sac tumor and immature teratoma mixed,1 case of yolk sac tumor embryonal carcinoma and teratoma mixed,1 case of choriocarcinoma and asexual cell carcinoma mixed,and 1 case of seminoma embryonal carcinoma and trophoblastic ingredients mixed.Conclusion：Although there is no specific by 64-slice spiral CT,to a certain degree,it can determine the benign or malignant tumor and give the important prop for clinical staging.
