肾母细胞瘤又称威尔姆斯瘤(Wilms′tumor),是一种胚胎性的恶性肿瘤,占小儿实体瘤的6%,占小儿肾脏肿瘤的95%。肾母细胞瘤生长迅速、恶性程度高、发生转移早,常可随血液转移至肺、肝脏等。手术等治疗方式可有效提高该病患儿的生存率,但肿瘤转移仍是其治疗难点。目前,CT检查是诊断肾母细胞瘤的主要方法,其具有较高的分辨率,不但可确定病变的位置、形态,还能准确测量病变大小,同时显 Wilms tumor, also known as Wilms’ tumor, is an embryonal malignant tumor accounting for 6% of pediatric solid tumors and 95% of pediatric kidney tumors. Wilms tumor rapid growth, high degree of malignancy, early metastasis, often with the blood to the lungs, liver and so on. Surgery and other treatment methods can effectively improve the survival rate of children with the disease, but tumor metastasis is still its treatment difficulties. Currently, CT examination is the main method of diagnosis of nephroblastoma, which has a higher resolution, not only to determine the location of lesions, morphology, but also accurately measure the size of the lesion, and was significantly
