A 7-year-old boy was seen at follow-up for a Wilms' tumor that had been treated by a right nephrectomy and a regimen of vincristine and dactinomycin at age 3 years. Subsequently, he had no major problems but complained of intermittent abdominal pain and constipation. He had not been taking medication. Nothing exacerbated or relieved the pain, and it spontaneously resolved without intervention. His bowel movements occurred every two to five days. The stool was hard and usually white.
Results of abdominal examination were normal. The hard stool, palpable by rectal examination, was guaiac-negative. The patient was in good health at the time of chest roentgenography. The roentgenograms showed multiple 1- to 3-cm ovoid opacities in the gastrointestinal tract (Figs 1 and 2).
