摘要
目的探讨儿童少见部位卵黄囊瘤的影像学表现及其相关临床特征。方法回顾性分析2例经病理确诊的卵黄囊瘤患儿的临床及CT资料,分析其影像学表现及特点。结果 2例卵黄囊瘤,1例发生于宫颈,1例发生于右侧膈肌,CT表现均为边界不清软组织肿块影,病理结合免疫组化染色诊断为卵黄囊瘤。结论卵黄囊瘤是少见的生殖细胞恶性肿瘤,发生于少见部位的卵黄囊瘤影像诊断更为困难,其确诊有赖于病理检查。
Objective To investigate the imaging features of yolk sac tumor in children and its clinical characteristics. Methods The clinical and radiological data of 2 yolk sac tumor patients were retrospectively collected, and the imaging and diagnostic features were analyzed. Results 1 case of yolk sac tumor was found in the cervix and 1 case in the dia- phragm. The CT images of both showed soft tissue mass without clear margins. The diagnosis of yolk sac tumor was made by pathology and immunohistochemical staining. Conclusion Yolk sac tumor is a kind of rare malignant germ cell tumor. The diagnosis is even more difficult when happened in rare places. The definite diagnosis relies on the pathological exami- nation.
