ABSTRACT
Objective To assess the imaging and clinical manifestations of gastrointestinal mucosa associated lymphoid tissue(MALT)lymphoma with review of literatures. Methods Six cases of gastrointestinal MALT lymphoma (4 in stomach and 2 in intestine) proved by surgery and biopsy were examined with gastrointestinal barium meal examination (GI), CT or MRI scans. Results Gastrointestinal MALT lymphoma was an indolent disease that patients had a slow natural course, a high response rate to treatment and a long survival. Most cases of gastrointestinal MALT lymphoma had associated with Helicobacter pylori. GI showed thickened folds, multiple mucosal nodularity or polypoid filling defects, multiple point ulcers, and enlarged areae gastricae. CT and MRI revealed diffuse gastrointestinal wall thickening, polypoid lesion, and abdominal lymphadenopathy.Two or more findings and multiplicity of lesions might be the most important imaging features. Conclusions Based on the typical imaging findings combined with clinical characteristics, gastrointestinal MALT lymphoma could be suggested.
