Abstract： 目的报告6例胃肠道黏膜相关淋巴组织(mucosa-associated lymphoid tissue, MALT)淋巴瘤并结合文献探讨其影像学表现.方法搜集经病理证实的胃肠道MALT淋巴瘤6例,其中来源于胃4例,十二指肠及回肠各1例,所有病例均经胃肠钡餐造影(GI)、CT或MRI检查.并复习了近几年国内外文献报道的胃肠道MALT淋巴瘤的临床及影像学表现.结果根据该组病例临床及影像学所见,胃肠道MALT淋巴瘤临床及影像学特征为:(1)年龄在50岁以上,多为Ⅰ～Ⅱ期低度恶性肿瘤,病程长,进展缓慢,症状轻,疗效好;(2)绝大多数幽门螺杆菌阳性,特别是胃MALT淋巴瘤;(3)GI示胃小区不规则增宽,多发性黏膜下小结节和多发边缘模糊的浅表溃疡,胃肠道黏膜皱襞粗大、紊乱迂曲,晚期呈多发息肉样结节、肿块及较大溃疡.CT及MRI表现为胃肠道壁环形光滑或小结节样增厚,肠MALT淋巴瘤可致肠腔狭窄.多发细小黏膜下病灶及多种征象共存是该病最重要的影像学特点.结论典型影像学表现结合临床表现,可作出胃肠道MALT淋巴瘤的诊断.
