Dr. White: This 48-year-old man was found to have values of 1+ for albumin and 2+ for bacteria and many red blood cells (RBC) on routine urinalysis. He denied any chest, abdominal, or urinary-tract symptoms. Roentgenograms of the chest and abdomen were obtained.
Dr. Joseph T. Ferrucci, Jr.: The chest is unremarkable except for a fibrotic scar or two in the upper lobe of the right lung. On the abdominal roentgenogram, the gas pattern is normal, and there is no hepatic or splenic enlargement. The renal outlines are poorly defined. The left kidney appears normal. There is a suggestion of a bulky soft-tissue mass in the lower pole of the right kidney, containing several areas of calcification.
