✦ Synopsis

This boy was referred to Oncology when 2 days old for evaluation of a left upper quadrant mass. He weighed 8 lb 1 I oz at birth, after a full-term gestation complicated only by a borderline high maternal alphafetoprotein. Serial ultrasound examinations during pregnancy were negative for spinal defects. A routine physical examination prior to circumcision when the boy was 1 day old detected a left upper quadrant mass. He had been progressing entirely normally, and evaluation at that time included ultrasonographic examination. This showed a renal mass in the upper pole with dilatation of the collecting system of the lower pole, and a chest X-ray film was normal. There was no family history of renal disease. He was transferred to this institution for further evaluation and therapy. At that time, he was a vigorous and entirely normal 2 day old child with a blood pressure of 101/67. Abdominal examination detected a firm, nontender, 3 X 3 cm round, firm mass in the left upper quadrant. No other abnormalities were detected. Laboratory examinations were within normal limits. Ultrasonography and an excretory urogram were performed.
