A boy with abdominal Burkitt's lymphoma developed rectal bleeding, abd
ominal distension, pain, and fever three weeks after diagnosis. Imagin
g studies revealed a necrotic tumor mass allowing a fistulous pathway
from the ileum to the proximal colon. A laparotomy was performed, with
resection of the large necrotic tumor. The child recovered, and has h
ad no further evidence of Burkitt's disease. The radiological evaluati
on performed in this case ensured proper medical management and surgic
al intervention during a life-threatening event. The possibility of bo
wel perforation as a complication of therapy for abdominal lymphoma mu
st be recognized.
