目的：探讨原发性小肠淋巴瘤的CT表现，以提高对该病的认识。方法：搜集经手术病理证实的原发性小肠淋巴瘤17例，术前均行CT平扫，12例加做增强扫描，通过对CT图像进行观察分析，总结其特点。结果：发病部位以回肠多见（包括累及回盲部）（n=15）。CT表现为肠壁广泛性增厚13例，其中8例肠腔呈“动脉瘤样扩张”；肠腔内软组织肿块4例，肠腔不同程度狭窄。增强扫描病变呈轻至中度强化，坏死少见。该两型中10例伴有周围和（或）肠系膜淋巴结肿大。继发改变主要包括肠梗阻、肠套叠、肠穿孔。结论：原发性小肠淋巴瘤的CT表现具有一定特征性，能清楚显示肠管壁增厚的程度、浸润范围、周围淋巴结情况及继发改变，对肿瘤的诊断有较大帮助。

To investigate the CT manifestations of primary small intestinal lymphoma, and to improve the knowledge of this disease. Methods: 17 cases of primary small intestinal lymphoma proved by pathology were collected. All cases were underwent CT plain scan and 12 cases were received enhanced scan.The CT characteristics of each patient were observed and analyzed. Results: Most of the cases were located seen in the ileum (including the ileocecal valve involved)(n=15). 13 cases displayed as intestinal wall thickening, in which there were 8 cases demonstrated that the intestinal cavity dialated as“aneurysm”. The other 4 cases showed as soft tissue masses in the cavity with luminal stenosis. All the lesions showed mild to moderate enhancement after contrast agent injection. Peripheral and/or mesenteric lymph nodes were showed in 10 cases. Conclusion: The CT manifestations of primary small intestinal lymphoma has certain characteristics. CT examination is helpful in diagnosis of it.
