目的探讨小肠淋巴瘤MSCT影像 诊断价值。方法 回顾性分析经手术、病 理证实的21例小肠淋巴瘤的多层螺旋CT平 扫和双期增强表现。结果 21例中，发病 部位以回肠末端最常见、占15例，空肠2 例，回肠近端2例，十二指肠2例。CT平扫 表现为肠壁不规则增厚，息肉样肿块形 成，肠腔扩张或狭窄，增强后病灶轻中度 强化，密度较均匀，很少坏死。结论 小 肠淋巴瘤的多层螺旋CT表现有一定特征 性，对鉴别诊断具有应用价值。

Objective To explore the diagnostic value of MSCT imaging in small intestinal lymphoma. Methods Both plain,dual-phase contrast enhanced MSCT were performed for 21 cases of small intestine lymphoma which confirmed by pathology. Results The most common lesion located in terminal ileum(15 cases), and 2 cases located at jejunum, 2cases at proximal ileal and the other 2 cases located at duodenum.CT scan characterized by irregular bowel wall thickening,polypoid tumor formation,expand or narrow lumen. All of the Lesions had mild-to-moderate enhancement after enhanced, and the density is uniform, rarely see signs of necrosis. Conclusion Small intestine lymphoma has certain MSCT features,and CT have application value for differential diagnosis.
