目的：探讨婴儿原发性肾脏肿瘤的不同影像特点及诊断。方法收集29例经病理证实的婴儿肾脏原发性肿瘤的影像进行回顾性分析。结果肾母细胞瘤24例，包括双侧性3例，平均月龄10个月，影像表现为单侧或双侧肾脏软组织密度肿块，不均匀强化，21例单侧病例中2例表现为多房囊性肿块，1例肿块内见脂肪密度；中胚层肾瘤3例，平均月龄2个月，2例具有包膜下积液的影像表现，1例术后1年复发；婴幼儿骨化性肾脏肿瘤1例，表现为肾脏含钙化肿块；透明细胞肉瘤1例，表现为肾脏巨大软组织密度肿块伴明显不均匀强化，未见骨转移征象。结论婴儿肾脏原发性肿瘤具有一定的年龄分布特征、影像特点，综合分析有利于术前准确诊断。

Objective To explore the clinical and imaging features of original tumors of kidney in infants .Methods We studied the clinical and CT imaging manifestations of 29 cases proved with surgery .Results Twenty‐four cases of nephro‐blastoma at a mean age of ten‐months are heterogeneous soft‐tissue‐attenuation masses within kidney ,and 3 cases of them are bilateral .Three cases of congenital mesoblastic nephroma at a mean age of two months present as renal masses with subcapsular effusion in two cases ,and one of them has a recurence within one year after postoperation .One case of ossif‐ying renal tumor of infancy displays a small‐size calcified mass .One case of clear cell sarcoma shows a large‐size heteroge‐neously enhanced mass but without bone metastasis .Conclusion Analyzing the different features about clinic and imaging of the original renal tumors in infants is useful for the preopertive diagnosis .
