CLINICAL HISTORY.—The patient was a 15-year-old girl who was sent to the Radiology Department of Childrens Hospital as an outpatient, because of a right lower quadrant mass which had been present for five years.
Her history did not suggest obstruction, and no other complaints were offered. The family history was of interest because there were four siblings who had died in infancy.
Physical examination disclosed a well developed and well nourished, though slightly small, adolescent who was in no distress. The only positive physical findings were limited to the abdomen. An easily palpable mass was present in the right lower quadrant. This was nontender and slightly movable. However, it did feel firm and smooth. No other abdominal findings of significance were noted.
No laboratory studies were performed at this time. A barium enema was done to evaluate the palpable mass (Fig 1 and 2).
