Abstract

The occurrence of primary duodenal mucosa associated lymphoid tissue (MALT) lymphoma is extremely rare, and more so is the obstruction of the duodenum for the MALT lymphoma. We describe the small bowel follow through and CT findings in an uncommon case of MALT lymphoma presenting with bowel obstruction of the 2nd portion of the duodenum and small bowels.

  Fig. 1 56-year-old male with MALT lymphoma presenting with bowel obstruction. A. Small bowel follow through shows focal luminal narrowing (long white arrows) of the 2nd portion of the duodenum with small ulceration. And, also noted smooth luminal narrowing with fold thickening at the distal jeunal loop (short white arrows) and the pelvic ileal loop (white arrowheads). B. Contrast enhanced CT at the level of the upper abdomen shows peripheral enhancing mass-like wall thickening (white arrows) of the 2nd portion of the duodenum with proximal luminal dilatation. C. Contrast enhanced CT at the level of middle abdomen shows enhancing wall thickening (white arrows) of the proximal jejunum with multiple enlarged mesenteric lymph nodes (white arrowhead). D. Contrast enhanced CT scan at the level of lower abdomen shows dumbell-shape luminal narrowing (white arrowheads) of the pelvic ileal loop. E. Follow-up CT after 10 months of chemotherapy shows improvement of wall thickening (white arrows) of the duodenum and small bowel loops. Multiple mesenteric lymph nodes are also improved (not shown).
