He had no immediate prior history of trauma or abdominal pain. His physical examination was unremarkable. Laboratory evaluation at that time was significant for microscopic hematuria on urinalysis. Renal ultrasound examination and abdominal CT were performed (figures 1 and 2). The patient was referred to a surgeon. Despite medical advice, surgery was delayed at the parents' insistence. Three weeks after initial presentation, the patient returned with acute right abdominal and flank pain. A repeat abdominal CT was followed by laparotomy (figures 3 and 4).Tuesday, 19 Sep 2000 16:46:39 GMT
