【摘要】：目的探讨小肠淋巴瘤的CT和MRI表现及其病理相关性。方法回顾性分析28例经病理证实的小肠淋巴瘤患者的CT和MRI资料。结果 28例均为非霍奇金淋巴瘤,B细胞淋巴瘤24例,T细胞淋巴瘤4例;共发现非连续病灶41个,肠壁浸润型病灶30个,肠系膜肿块型7个,洞穴型3个,息肉肿块型1个。6例病变肠段管腔呈动脉瘤样扩张。20例伴腹腔淋巴结肿大,明显包绕肠系膜血管呈"夹心面包征"8例。其他器官受累共7例。14例弥漫大B细胞淋巴瘤中12例发生于回肠,4例T细胞淋巴瘤中3例发生于空肠,1例发生于十二指肠;2例T细胞淋巴瘤为浸润型,其肠壁增厚均不明显;14例弥漫大B细胞淋巴瘤均未见穿孔;3例T细胞淋巴瘤淋巴结肿大不显著。结论均匀较长节段的肠壁增厚、肠腔呈动脉瘤样扩张、明显的肠系膜淋巴结肿大并包绕肠系膜血管呈"夹心面包征"的典型征象有助于小肠淋巴瘤的正确诊断。
[Abstract]:Objective to investigate CT and MRI manifestations of small intestinal lymphoma and its pathological correlation. Methods Retrospective analysis of 28 cases of CT and MRI data of patients with small intestinal lymphoma confirmed by pathology. Results 28 cases were non Hodgkin lymphoma, 24 cases of B cell lymphoma, 4 cases of T cell lymphoma; non continuous were found in 41 lesions, bowel wall invasion type 30 lesions, mesenteric mass type 7, cave type 3, type 1.6 cases of polyp mass lesions of the bowel lumen showed aneurysmal dilatation of.20 patients with abdominal lymph node enlargement, was wrapped around the mesenteric vessels were "sandwich" sign in 8 cases. The other organ involved a total of 7 cases of.14 patients with diffuse large B cell lymphoma in 12 cases occurred in the ileum, 4 cases of T cell lymphoma in 3 cases occurred in the jejunum, 1 cases occurred in the duodenum; 2 cases of T cell lymphoma infiltrating type, the bowel wall thickening was not obvious; 14 cases of diffuse large B cell lymphoma were no perforation; 3 cases of T cell lymphoma Lymph node enlargement was not significant. Conclusion the uniform thickening of the intestinal wall long segments of the intestinal lumen showed aneurysmal dilatation, mesenteric lymph node enlargement of mesenteric vascular encasement of typical signs of a "sandwich" sign is helpful to the correct diagnosis of small intestinal lymphoma significantly.
