摘　　要：目的　探讨肠道恶性淋巴瘤的影像特点。方法　复习经手术及病理证实的肠道恶性淋巴瘤 3 2例 ,其中X线钡餐 2 0例 ,双对比灌肠 12例 ,CT扫描 10例 ,B超 19例。结果　钡剂造影发现小肠或回盲受累 2 0例 ,包括小肠局部扩大 6例 ,腔内多发息肉状增生 7例 ,肠壁浸润 4例 ,腔内增生伴溃疡 3例。病灶局限于大肠者 12例 ,分别是腔内肿块 6例 ,肠腔狭窄 5例和粘膜粗大 1例。 10例CT中见肠壁不规则增厚 5例 ,腔内偏侧肿块 2例 ,肠扩大伴壁厚 3例。B超发现异常 13例 ,其中肠壁增厚的条状低回声 5例 ,假肾征 6例 ,团状低回声 2例。结论　肠道淋巴瘤的X线、CT、超声表现各有特点 。Objective To explore the imaging characteristics of malignant lymphoma of intestinal tract.Methods Thirty-two cases of malignant intestinal lymphoma proved operatively and pathologically were studied .All cases were subjected to Ba-meal or double contrast Ba-enema examinations. There were 10 cases studied by CT scan and 19 cases by B-ultrasonography.Results By Barium studies we found 20 cases of lesions involving the small intestine or ileocecal junction and 12 involving the large intestine. In the former subgroup , we found regional dilatation of small intestine in 6, multiple intraluminal polypoid filling defects in 7, intestinal wall infiltration in 4, intraluminal nodular proliferation with ulcer formation in 3; while in the latter subgroup ,there were polypoid masses seen in 6, narrowing of intestinal lumen in 5 and coarse intestinal mucosa in 1.On CT scan , we found irregular thickening of intestinal wall in 5 cases , eccentric intraluminal mass in 2 and intestinal dilatation associated with thickening of intestinal wall in 3. B-ultrasonography showed beltoid low echo thickened intestinal wall in 5 cases ,pseudo kidney sign in 6 and lumpy low echoes in 2. Conclusion Barium study , CT scan and B-ultrasonography have different specific diagnostic characteristics for malignant intestinal lymphoma.In combination with these examinations are mutually beneficial in the diagnostic process.
