摘要 目的探讨小儿肾母细胞瘤(Wilmstumor,WT)的超声图像特征,以便早期准确诊断,及时给予干预。方法回顾性分析5年内经作者超声检查获首先诊断,并经手术及病理检查证实的69例Wilms瘤患儿超声检查及临床资料。结果患儿年龄11d至16岁,其中0—4岁占78%(54/69)。单侧68例(肿块位于肾脏上极28例,下极32例,中央7例,肾盂内1例);双侧1例,两侧均位于肾脏中央。肿瘤均呈团块、分叶状改变,表现为中等或中等偏低回声,大多数内部回声不均质伴有大小不等的无回声区或弱回声区,少数为完全实质性,瘤体内无钙化灶出现。彩色多普勒频谱显示不规则高阻低速血流。47例边界清楚,周边可见残存肾实质,与肿瘤形成“握球征”。存在同侧肾静脉和下腔静脉瘤栓4例(其中1例通过膈肌进入右心房)。结论超声影像学检查对典型WT具有较高的诊断价值,可以定位、显示内部结构,并能检测肾静脉、下腔静脉等大血管内是否有瘤栓存在,无辐射,可重复,是理想的首选检查手段。
