摘　　要：目的提高对小儿腹部内胚窦瘤CT表现的认识.方法回顾性分析23例经手术病理证实的小儿腹部内胚窦瘤的临床和CT资料.结果 23例CT平扫均表现为实性肿块,18例肿块表现为不均质密度,5例表现为均质密度.19例增强CT扫描表现为中～高度不均匀强化,其中9例表现为周边部的不规则条状及网状强化.结论 CT对小儿腹部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进行鉴别.Objective To study the CT manifestation of abdominal endodermal sinus tumor in childhood. Methods Twenty-three cases of abdominal endodermal sinus tumor in children were retrospectively reviewed. Results All cases revealed solid masses on plain CT scan. The density of the tumor was heterogeneous in 18 cases and homogeneous in 5 cases, The masses showed moderate to high heterogeneous enhancement after administration of contrast material in 19 cases, and 9 out of 19 cases showed irregular reticular enhancement. Serum α-fetoprotein （AFP） was elevated to more than 1210μg/L in all cases （ normal ： less than 20μg/L ）. Conclusion CT is a valuable tool in the diagnosis of abdominal endodermal sinus tumor in children. CT combined with serum AFP can give rise to the diagnosis of the disease.
