儿童肾母细胞瘤的CT诊断及分期

目的:评价CT对儿童肾母细胞瘤的诊断及分期中的价值。方法:总结27例临床影像资料完整、经手术病理证实的肾母细胞瘤的临床CT表现。结果:共在33个肾脏中检出原发肿瘤36个,右肾11例,左肾10例,双肾6例;36个肾母细胞瘤中病理组织学类型包括上皮型10例,胚芽型7例,间质型9例,混合型7例,间变型3例;术前分期Ⅰ期9例,Ⅱ期7例,Ⅲ期3例,Ⅳ期2例,Ⅴ期6例,术前分期的准确率为88.89%。结论:CT检查可清晰显示肿瘤的轮廓,精确确定病灶部位,测量病灶大小,并可准确判断肿瘤的侵犯范围、转移灶,对肾母细胞瘤的定性、分期、评估预后及随访有重要价值。

CT diagnosis and staging of nephroblastoma in children

Objective:To evaluate the value of CT in diagnosing and staging of nephroblastoma in children.Methods:Clinical and CT manifestations of nephroblastoma in 27 cases with integrate imaging material proved operatively and pathologically were summarized.Results:Thirty-six primary tumors were found in 33 kindeys,11 in the right kidney,10 in the left kidney,and 6 in both kidneys.The pathological result of the 33 cases includes epithelial type(10 cases),blastemal type(7 cases),stromal type(9 cases),composite type(7 cases),anaplastic type(3 cases),The preoperative staging of the tumor:stage I in 9 cases,stage II in 7 cases,stage III in 3 cases,stage IV in 2 cases,and stage V in 6 cases.The accurate rate of tumor staging was nearly 88.89%.Conclusions:The CT inspection can show edge,site,size of the tumor,and accurately evaluate tumor invasion,metastasis.It has important value to determine the nature,staging,following-up of nephroblastoma.
