Neonoblastoma is also known as renal embryos, Wilms tumor, originated in the undifferentiated posterior renal embryo base, can form a variety of components of the kidney. It shows Kidney cell tumor accounts for more than 80% of children under 15 years of age with malignant genitourinary tumors, accounting for about 8% of children's solid tumors. Statistics of domestic 6 pediatric hospital 2133 cases of malignant solid tumors, there are 503 cases of nephroblastoma (24%), the diagnosis of age 1 to 5 years old accounted for 75%, the highest age is 1 to 3 years old, the average age is 3.1 year old. 90% of cases diagnosed when the age is less than 7 years old, rare in adults and newborns.

This study aims to investigate the imaging findings of B-ultrasonography, CT and MRI in nephroblastoma. Methods: Eight patients were examined by this study, and the lesion size, edge, internal structure and enhancement were observed. The results of the examination have the same, but the degree of display and subtle structure is different. Through medical images can be on the examination of the disease can make a diagnosis, MR the most diagnostic value. Comprehensive data can significantly improve the diagnostic accuracy.
