摘要
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。
Abstract
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.
