摘要
目的探讨儿童肾癌的ＣＴ诊断。方法回顾性分析７例经手术病理证实为儿童肾癌的ＣＴ表现。男４例，女３例；年龄３～１３岁，平均年龄９岁。全部病例行平扫与增强检查。结果儿童肾癌具有学龄期发病优势，这有别于Ｗｉｌｍｓ瘤好发于学龄前期。儿童肾癌的ＣＴ表现与Ｗｉｌｍｓ瘤极为相似而难以区分者３例；２例小肾癌表现颇具特征，ＣＴ平扫呈轻度高密度影，增强后轻度强化；表现为巨大类囊性低密度肿块（直径＞１０ｃｍ）２例。结论临床特点与ＣＴ表现相结合。
Purpose To analyze the CT manifestations of children renal cell carcinoma(CRCC) with review of literature. Methods CT manifestations in 7 cases of CRCC proved operatively and pathologically were studied retrospectively. There were 4 males and 3 females, the median age was 9 years(range,3 to 13 years), All patients received CT scan before and after enhancement with intravenous contrast medium. Results The incidence of CRCC seemed to have a predilection for school age, which was different from Wilms' tumor. The common features of CRCC found in this series were exactly like those of Wilms tumor in three cases. Two cases of small CRCC (diameter <3cm)showed CT characteristics: slightly hyperdense with mild enhancement after contrast administration. Large cystic lucencies represented necrosis within the tumor appeared in two cases(diameter>10cm). Conclusion The diagnosis of CRCC can be established by close combination of CT findings and clinical manifestations.
