目的:探讨多层螺旋CT对原发性胃肠道淋巴瘤(PGIL)的诊断及鉴别诊断价值。方法:对我院经手术病理证实的原发性胃肠道淋巴瘤40例,临床影像学资料进行回顾性分析。结果:40例胃肠道淋巴瘤均为非霍奇金淋巴瘤,其中胃淋巴瘤31例,肠道淋巴瘤9例。多层螺旋CT表现胃壁弥漫性均匀增厚19例,均清晰显示“黏膜白线征”及“轨道征”。病变处胃肠道管壁增厚与管腔狭窄呈非一致改变39例。肠道“动脉瘤样扩张”4例。“汉堡包征”1例。临床影像学很少出现梗阻表现。结论:充分认识原发性胃肠道淋巴瘤典型的CT影像特征,有助于提高病变的术前诊断正确率。
Objective: To investigate the value of multi-slice spiral CT in the diagnosis and differential diagnosis of primary gastrointestinal lymphoma (PGIL). Methods: Forty patients with primary gastrointestinal lymphoma confirmed by surgery and pathology in our hospital were retrospectively analyzed with clinical imaging data. Results: All 40 cases of gastrointestinal lymphoma were non-Hodgkin’s lymphoma, including 31 cases of gastric lymphoma and 9 cases of intestinal lymphoma. Multi-slice spiral CT showed diffuse gastric evenly thickening in 19 cases, all clearly show “mucosal white line sign ” and “orbit sign ”. Lesions in gastrointestinal wall thickening and stenosis was inconsistent change in 39 cases. Gut “aneurysm-like dilatation” in 4 cases. “Hamburger sign ” in 1 case. Clinical imaging rarely appear obstructive performance. Conclusion: A full understanding of the typical features of CT images of primary gastrointestinal lymphoma, help to improve the accuracy of preoperative diagnosis of lesions.
