【摘要】：目的回顾性分析胃淋巴瘤的CT影像及病理分型资料,提高对本病的CT征象的认识。方法对32例病理确诊的胃淋巴瘤的CT影像资料进行回顾性分析,比较不同病理类型之间的CT影像特点。结果 32例胃淋巴瘤均为B细胞性非霍奇金淋巴瘤,其中12例为黏膜相关淋巴组织B细胞淋巴瘤(MALT),20例为弥漫性大B细胞性淋巴瘤(DLBCL)。在胃病变范围、肿瘤坏死、黏膜破坏、淋巴结转移等方面,MALT与DLBCL之间均差异无统计学意义。在胃壁增厚方面,DLBCL胃壁增厚更明显,与MALT之间差异有统计学意义。所有突破胃浆膜层侵犯腹腔的胃淋巴瘤均为DLBCL。结论胃淋巴瘤的CT影像,在MALT和DLBCL之间存在一定的差异。CT对于胃淋巴瘤的诊断和鉴别诊断具有一定的价值。
[Abstract]:Objective to retrospectively analyze the CT imaging and pathological classification of gastric lymphoma and to improve the understanding of CT signs of gastric lymphoma. Methods the CT imaging data of 32 cases of gastric lymphoma diagnosed by pathology were analyzed retrospectively. Results 32 cases of gastric lymphoma were B-cell non-Hodgkin 's lymphoma, 12 of which were mucosa-associated lymphoid tissue B-cell lymphoma (malt). There were 20 cases of diffuse large B cell lymphoma (DLBCLN). They were gastric lesions, tumor necrosis, mucosal destruction, lymph node metastasis, and so on. There was no significant difference between MALT and DLBCL in gastric wall thickening. All gastric lymphomas that break through the gastric serosal invasion are DLBCL.Conclusion CT images of gastric lymphoma are significant. There are some differences between MALT and DLBCL. Ct has certain value in the diagnosis and differential diagnosis of gastric lymphoma.

【正文快照】： 胃是结外淋巴瘤的好发部位之一,胃淋巴瘤是胃内除胃癌以外发病率最高的恶性肿瘤,占胃肠道恶性淋巴瘤的48%~63%[1-2]。但胃淋巴瘤的临床发病率并不高,近几年与胃淋巴瘤影像表现有关的研究报道病例数也不多,相当一部分文献的样本数是20例以内[3-5]。为了提高对胃淋巴瘤的进一步
