摘　　要：目的:提高16排螺旋CT诊断小肠淋巴瘤的正确率。方法:回顾性分析经手术和病理证实的11例小肠淋巴瘤的16排螺旋CT表现。主要重建方法有多平面重建法(MPR)及最大密度投影法(MIP)。结果:11例肿瘤中发病部位以回肠最常见,占8例。主要征象有肠壁增厚7例,其中5例见肠腔呈动脉瘤样扩张。肠腔内息肉样肿块4例。肠系膜多发淋巴结肿大6例,其中3例见“夹心面包征”。2例继发肠套叠、肠梗阻。合并其他脏器受侵2例。结论:小肠淋巴瘤的CT表现具有一定特征,16排螺旋CT扫描及重建对小肠淋巴瘤诊断具有重要价值。Objective： To improve the accuracy rate of 16-detector row CT in diagnosing small intestinal lymphoma. Methods： The 16-detector row CT findings in 11 cases of small intestinal lymphoma proved by surgery and pathology were analyzed retrospectively. The main reconstruction techniques were multiplanar reformation（MPR） and maximum intensity projection（MIP）. Results： The most frequent location of the diseases was at ileum（8/11）. The main signs were bowel-wall thickening （n=7）, 5 of the 7 cases showed aneurysmal sign. Four cases showed luminal polypoid mass, 6 cases were found to have mesenteric lymph nodes, 3 of the 6 cases showed ＂sandwich＂ sign. Two cases were combined with intussusception and ileus. Two cases showed other organs involved. Conclusion： The CT finds of small intestinal lymphoma were definitely characteristic, 16-detector row CT and reconstructions had important value in diagnosing small intestinal lymphoma.
