title: Lymphoma of the small intestine: radiological appearances.
abstract: The radiological features of small intestinal lymphoma are described in 11 patients examined using the small bowel enema technique. The signs include luminal narrowing with mucosal destruction and occasionally shouldering of the margins and stricture formation, broad based ulceration, cavitation, non-specific thickening of the valvulae conniventes, discrete intraluminal filling defects, and a mass. In one patient, small nodules were scattered throughout the small intestine. Aneurysmal dilatation of a segment of intestine was seen in one case and an extraluminal mesenteric mass in another. A combination of different signs was a frequent finding and multiple intestinal lesions were present in four cases. Predisposing factors were present in five cases including coeliac disease, chronic lymphatic leukaemia, immunoproliferative small intestinal (alpha-chain) disease and previous extraintestinal lymphoma. In another patient there was evidence of extraintestinal lymphoma at the time of presentation.
