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。

Methods Retrospective analysis of 23 cases of pathologically confirmed pediatric abdominal endodermal sinus tumor clinical and CT data. Results CT scan showed solid mass in all 23 cases, heterogeneous mass in 18 cases and homogeneous density in 5 cases. 19 cases of enhanced CT showed moderate to high degree of uneven enhancement, of which 9 cases showed the irregular peripheral stripes and reticular strengthening.
