Intestinal Mucosal-Associated Lymphoid Tissue Lymphoma Mimicked Cryptogenic Multifocal Ulcerous Stenosing Enteritis

Abstract

Small-bowel barium enema showed multiple ulcerations and stenosis in the jejunum and proximal hold-up [Figure 1]a. Computed tomography (CT) confirmed the presence of multiple jejunal strictures, prestenotic dilation, and bowel wall thickening [Figure 1]b. The 18F-fluorodeoxyglucose positron emission tomography-CT (PET-CT) suggested intestinal inflammation. The appearance of skip lesions made us consider a rare disease called cryptogenic multifocal ulcerous stenosing enteritis (CMUSE). [...]the patient was treated with 40 mg daily prednisone, which was slowly tapered. According to the clinicopathological analysis of 143 primary intestinal lymphomas,[1] tumorous type was the most common pattern (86.7%).
