Primary Small Intestinal Diffuse Large B-cell Lymphoma Masquerading as Crohn's Disease: A Case Report

Six months later, CT enterography showed multiple thickening of the small intestine wall, and the descending and sigmoid colon, along with multiple air sacs, lumen stenosis, celiac lymph node enlargement, and small intestine incomplete torsion. In November 2014, small intestine CT enterography showed local lumen stenosis in the jejunum, obstruction of the duodenum and jejunum, thickening of the intestine wall, mesenteric whirlpool sign, and increased and enlarged mesenteric lymph nodes. Diffuse large B-cell lymphoma, a subtype of small intestine non-Hodgkin's lymphoma, is the most frequent pathological type in the stomach and intestine,[2] and because of missed diagnoses, only 30-40% of patients with early primary gastrointestinal non-Hodgkin's lymphoma receive surgery.
