Figure 7. Infective enteritis in a 3-year-old boy 1 week after autologous bone marrow transplantation for neuroblastoma. CT image shows diffuse small- and large-bowel wall enhancement with focal wall thickening in the jejunum and descending colon (arrows). The differential diagnosis included chemotherapy-induced mucositis, but GVH disease was excluded because the transplant was autologous.
