摘　　要：目的提高对小儿睾丸内胚窦瘤CT表现的认识。方法回顾性分析16例经手术病理证实的小儿睾丸内胚窦瘤的临床和CT资料。结果16例CT平扫均表现为睾丸实性肿块,14例肿块表现为均质密度,2例表现为不均质密度。12例CT增强扫描均表现为明显不均匀强化,其周边部强化明显。结论CT对小儿睾丸内胚窦瘤具有一定的诊断价值,结合血清甲胎蛋白测定有助于与其他肿瘤的鉴别。Objective To study the CT manifestation of testicular endodermal sinus tumor in childhood. Methods Clinical and CT data in sixteen cases of testicular endodermal sinus tumor in children were retrospectively reviewed . Results The tumors appeared as solid masses on plain CT scan , the density of the tumor was homogeneous in 14 cases and heterogeneous in 2 cases . The masses were obviously heterogeneous enhancement after administration of contrast material in 12 cases . Serum α- fetoprotein（ AFP） level was elevated to more than 1000μg/L（ normal： less than 20μg/L）. Conclusion CT is a valuable in diagnosis of testicular endodermal sinus tumor in children. CT combined with serum AFP can improve the diagnosis of the disease.
