摘要
目的 分析小儿生殖细胞瘤的CT表现特点 ,提高CT诊断的准确性。资料与方法 回顾性分析 38例生殖细胞瘤的CT表现 ,并与手术及病理结果进行对照。结果 多种组织成分组成的混杂密度占位 18例 ,囊性或以囊性为主的占位 12例 ,软组织密度或绝大部分为软组织密度的占位 8例。其中良性 2 8例 ,恶性 10例。良性均为成熟畸胎瘤。恶性组中内胚窦瘤合并畸胎瘤 3例 ;未成熟畸胎瘤、无性细胞瘤、内胚窦瘤各 2例 ;卵巢绒毛膜癌 1例。结论 小儿生殖细胞瘤的CT表现具有各自的特点 ,CT诊断准确性较高 ,为首选的检查方法。
Objective To analyze CT features of germ cell tumors in children and to improve its diagnostic accuracy.Materials and Methods Both plain CT (n=38) and contrast enhanced CT (n=11) findings in 38 children with pathologically proved germ cell tumors were retrospectively analyzed. The signs were compared with surgical and pathological results.Results Of 38 cases, mixed density lesion constituted by various tissues was seen in 18, cystic or mainly cystic lesion in 12 and soft tissue or mainly soft tissue density lesion in 8 cases. Twenty eight tumors were benign, all of them were mature teratomas, and the other 10 tumors were malignant, including endodermal sinus tumor combined with teratoma (n=3), immaturity teratoma (n=2), dysgerminoma (n=2), endodermal sinus tumor (n=2) and ovarian choriocarcinoma (n=1).Conclusion Each kind of germ cell tumors in children has its own CT characteristics. CT exam carries high diagnostic accuracy for the disease and should be taken as first choice.
