Objective: This article illustrates the characteristic CT findings of bowel damage related to drug toxicity, conditioning regimen, infections, and graft-versus-host disease (GVHD) in patients after hematopoietic stem cell transplantation.
Conclusion: Although some overlap exists in the CT appearances of the different causes of bowel wall inflammation, the findings are frequently unique enough to suggest a specific diagnosis. Awareness of the specific time of occurrence, intensity of clinical symptoms, preferred localization, and extent of accompanying extraintestinal findings help to distinguish the different pathologic entities.
