abstract: Imaging of the gastrointestinal complications of systemic chemotherapy

Abstract:

Gastrointestinal complications of chemotherapy may be serious and potentially life-threatening. Familiarity with and awareness of the potential complications associated with various chemotherapeutic agents/regimens is paramount to enable accurate and timely diagnosis. In this article we review the radiological manifestations of the most notable gastrointestinal complications associated with chemotherapeutic administration.

Conclusion

Figure 1. A 70-year-old woman on day 10 of idorubicin and cytosine arabinoside chemotherapy for acute myeloid leukaemia developed vomiting, abdominal pain, loose bloody stool, and was profoundly neutropenic. Intravenous contrast-enhanced CT demonstrates diffuse colonic mural thickening (black arrow), with surrounding mesenteric stranding (white curved arrow) and ascites (black curved arrow). The distribution is pan-colonic. This constellation of clinical and radiological findings is highly suggestive of neutropenic enterocolitis.
