The use of B mode ultrasound in the preoperative evaluation of abdominal masses in the pediatric age group is described. Using this technique it is possible to delineate the extent and site of origin of the mass. Cystic lesions can be distinguished from tumors by the degree of echo penetrance through the mass and the pattern of echoes within the mass. Lesions such as hydronephrosis and renal cysts were successfully distinguished from neuroblastomas and Wilm's tumors preoperatively. B mode ultrasound was felt to be of as much value as arteriography, which was performed in many of the cases.
