Imaging of gastrointestinal lymphoma.
The gastrointestinal (GI) tract contains the largest collection of lymphocytes anywhere in the body. GI lymphoma may arise at any site in the GI tract but typically involves the stomach and small bowel in cases of systemic disease. Most cases are non-Hodgkin B-cell type. Enteropathy-associated T cell lymphoma can complicate celiac disease. Less commonly, lymphoma may originate in the GI tract without systemic involvement. This sometimes occurs in response to chronic infections. This article discusses the role of imaging in detecting and staging GI tract lymphomas, using fluoroscopy and cross-sectional imaging, primarily CT.
