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.
本文描述了11例采用小肠灌肠技术检查的小肠淋巴瘤患者的放射学特征。其征象包括管腔狭窄伴黏膜破坏，偶尔可见边缘呈“肩部”状及狭窄形成、基底较宽的溃疡、空洞形成、黏膜皱襞非特异性增厚、腔内离散性充盈缺损及肿块。1例患者小肠内散在小结节。1例可见一段肠管呈动脉瘤样扩张，另1例可见肠系膜腔外肿块。不同征象合并出现很常见，4例存在多处肠道病变。5例存在易感因素，包括乳糜泻、慢性淋巴细胞白血病、免疫增殖性小肠（α链）病及既往肠外淋巴瘤。另1例患者在就诊时即有肠外淋巴瘤的证据。
