ABSTRACT

Gastrointestinal lymphomas can occur in nodular, polypoid, cavitary, ulcerative or diffuse infiltrating (submucosal) forms. Barium studies and computed tomography (CT) are the most popular imaging techniques used to diagnose these lymphomas. Barium studies are superior to CT in evaluating mild mucosal and submucosal changes. However, CT is the technique of choice because it provides a complete evaluation of the extent of disease dissemination, recent disease development, therapeutic response, and related complications.
