CLINICAL HISTORY.—An 8-year-old girl was seen by her family physician because of anorexia and a 2-lb weight loss. The child drank large quantities of milk but seemed to become full with relatively small amounts of solid foods. The physician palpated a hard mass in the left upper quadrant. The child was referred to the Children's Hospital of Los Angeles with a provisional diagnosis of abdominal neoplasm.
The presence of a large palpable mass in the left upper quadrant was confirmed. It was extremely firm and movable. Its position was more medial than one would expect with an enlarged spleen. The liver was not enlarged and there was no adenopathy. No abnormalities were detected in the studies of the urine and blood.
An intravenous urogram was performed, the findings of which were thought to be diagnostic of a specific abnormality which was subsequently confirmed by other studies.
