目的：探讨原发性胃肠道淋巴瘤（PGIL）的多层螺旋CT（MDCT）表现，以提高该病的诊断和鉴别诊断水平。方法收集36例复旦大学附属肿瘤医院2006年1月—2014年6月经病理证实的PGIL患者资料，总结其CT特征表现及诊断和鉴别诊断要点。结果36例PGIL均为非霍奇金淋巴瘤（NHL），28例为弥漫大B细胞淋巴瘤（DL-BCL），8例为黏膜相关淋巴组织（MALT）淋巴瘤。病变位于胃20例，空、回肠10例，十二指肠3例，回盲部2例，直肠1例。CT检查示32例胃肠道管壁呈弥漫增厚伴均匀强化，周围常有肿大淋巴结影；4例胃壁局限性增厚呈结节、肿块影。动脉瘤样扩张是肠道淋巴瘤的特征性表现。病灶周围增粗血管或增粗血管穿行于病灶是胃肠道淋巴瘤的重要表现。结论 PGIL的CT表现有一定特征性，有望提高诊断正确率。
目的：探討原髮性胃腸道淋巴瘤（PGIL）的多層螺鏇CT（MDCT）錶現，以提高該病的診斷和鑒彆診斷水平。方法收集36例複旦大學附屬腫瘤醫院2006年1月—2014年6月經病理證實的PGIL患者資料，總結其CT特徵錶現及診斷和鑒彆診斷要點。結果36例PGIL均為非霍奇金淋巴瘤（NHL），28例為瀰漫大B細胞淋巴瘤（DL-BCL），8例為黏膜相關淋巴組織（MALT）淋巴瘤。病變位于胃20例，空、迴腸10例，十二指腸3例，迴盲部2例，直腸1例。CT檢查示32例胃腸道管壁呈瀰漫增厚伴均勻彊化，週圍常有腫大淋巴結影；4例胃壁跼限性增厚呈結節、腫塊影。動脈瘤樣擴張是腸道淋巴瘤的特徵性錶現。病竈週圍增粗血管或增粗血管穿行于病竈是胃腸道淋巴瘤的重要錶現。結論 PGIL的CT錶現有一定特徵性，有望提高診斷正確率。

Objective To describe the multi-detector computed tomography (MDCT) features of primary gastrointestinal lymphoma (PGIL), and to improve the diagnosis and differential diagnosis ability.Methods A total of 36 cases of PGIL confirmed by pathological examination in Fudan University Shanghai Cancer Center from January 2006 to June 2014 were selected. Combining with literatures, the 36 patients’ CT images were analyzed retrospectively.Results All PGILs belonged to non-Hodgkin’s lymphoma (NHL), 28 with diffuse large B-cell lymphoma (DLBCL) and 8 with mucosa-associated lymphoid tissue (MALT) lymphoma. 20 lesions were located in stomach, 10 lesions in jejunum and ileum, 3 lesions in duodenum, 2 lesions in ileocecal junction, and 1 lesion in rectum. Thickening of the wall of the gastrointestinal tract with homogeneous enhancement was the typical feature of PGIL which was shown in 32 cases. Meanwhile tumescent lymph nodes were also shown. Aneurysmal dilatation was the characteristic feature of intestinal lymphoma. Enlargement or thickening vessel around lesion was an important manifestation of gastrointestinal lymphoma. Conclusion PGIL has specific MDCT features, and MDCT is helpful in improving diagnosis rate.
