A variety of pediatric renal masses may be differentiated from Wilms tumor on the basis of their clinical and imaging features. Wilms tumor is distinguished by vascular invasion and displacement of structures and is bilateral in approximately 10% of cases. Nephroblastomatosis occurs most often in neonates and is characterized by multiple bilateral subcapsular masses, often associated with Wilms tumors. Renal cell carcinoma is unusual in children except in association with von Hippel{u2013}Lindau syndrome and typically occurs in the 2nd decade (Verswijvel et al., 2004). Renal masses are being discovered with increasing frequency due to advances of cross-sectional imaging studies being performed in clinical practice. Accurate characterization of renal masses is essential to ensure appropriate case management, to assist in staging and prognosis and to differentiate surgical lesions from nonsurgical lesions. In general, if a lesion cannot be characterized as benign or malignant, it should be considered malignant
