摘要 目的:探讨婴幼儿肾脏肿瘤的CT表现及其诊断价值.方法:回顾性分析经病理证实的24例婴幼儿肾脏肿瘤的临床及CT资料,总结分析肿瘤的类型及CT表现.结果:24例中,肾母细胞瘤17例,CT表现为单侧肾脏内混杂密度肿块伴较明显囊变坏死,强化不均匀;2例伴钙化,1例肿块内见脂肪密度;2例伴肾静脉或下腔静脉癌栓,3例伴远处转移(肺、肝脏、骨、胸壁及淋巴结转移).中胚层肾瘤2例,CT表现为肾脏内软组织密度结节,密度欠均匀,中度强化.透明细胞肉瘤1例,CT表现类似肾母细胞瘤,坏死更显著.乳头状淋巴管内血管内皮瘤1例,CT表现为肾脏内类圆形低密度灶不均质轻度渐进性强化.XP11.2易位性肾癌1例,CT表现为单侧肾脏混杂密度肿块,内有点状钙化,轻度不规则强化,伴腹膜后转移.淋巴瘤2例,其中Burkitt瘤1例,CT表现为双肾多发等密度结节,轻度强化;肝脏内多发低密度灶,轻度强化;急性髓系白血病侵犯肾脏1例,CT表现为单侧肾脏、腹腔、腹膜后、肠系膜及胸壁多发巨大不规则软组织密度肿块.结论:肾母细胞瘤多发于1岁以上的婴幼儿;中胚层肾瘤多发生在1岁内.婴幼儿肾脏肿瘤的诊断参考临床资料结合CT表现,可提高术前诊断准确率.
