摘　　要：目的 分析MSCT增强扫描在胃肠道黏膜相关淋巴组织（MALT）淋巴瘤诊断中的应用价值.方法 回顾性分析经病理证实的11例胃肠道MALT淋巴瘤的临床和影像资料,分析病变部位、形态表现、增强表现、淋巴结肿大及其他结外器官的受累情况等.结果 （1）形态表现：弥漫性增厚型8例（72.7%）,其中胃5例,肠3例;局限性肿块/结节型3例（27.3%）,其中胃2例,肠1例;肿瘤导致管腔＂动脉瘤样扩张＂2例,均发生于肠道;另有1例回盲部局限性肿块/结节型,病灶致局部肠腔狭窄.（2）增强表现：10例（90.9%）中度或明显强化,9例（81.8%）均匀强化.（3）淋巴结及其他结外器官受累情况： 5例（45.5%）累及区域淋巴结,1例（9.1%）累及区域淋巴结及膈下远处淋巴结,1例（9.1%）同时累及膈肌两侧淋巴结;2例（18.2%）伴有其他结外器官受累.（4）临床分期：Ⅰ~Ⅱ期9例（81.8%）,Ⅳ期2例（18.2%）.结论 MSCT增强扫描可为胃肠道MALT淋巴瘤的诊断和分期提供可靠依据,建议将胸部和腹盆腔联合增强扫描作为常规检查项目.Objective To analyze the application value of MSCT enhanced scanning in diagnosis of gastrointestinal mucoca associated lymphoid tissue（MALT） lymphoma.Methods 11 cases of gastrointestinal MALT lymphomas confirmed by pathology were analyzed retrospectively.The clinical data and imaging features of 11 cases were analyzed,including lesion sites, morphologic features and enhancement patterns of tumors,positions of lymph nodes,involvement of extranodal site excluding gastrointestinal tract.Results For morphologic features,8 cases （72.7%） were gastrointestinal wall thickening type, among them, 5 cases occurred in the stomach and 3 cases in the intestine;3 cases （27.3%） were localized mass/nodule type, among them, 2 cases occurred in the stomach and 1 case occurred in the intestine.The sign of aneurysmal dilatation was showed in 2 cases, which occurred in the intestinal tract.There was 1 case of localized mass/nodule MALT lymphoma in the ileocecal junction with local intestinal lumen stenosis.For the manifestations of enhanced scanning,10 cases （90.9%） of tumors were moderately or obviously enhanced, 9 cases （81.8%） showed homogeneous enhancement.For the involvement of lymph nodes and other extranodal organs, regional lymph nodes were involved in 5 cases（45.5%）, regional lymph nodes and distant lymph nodes were involved in 1 case（9.1%）, lymph nodes of both sides of the diaphragm were involved in 1 case （9.1%）, extranodal sites excluding gastrointestinal tract were involved in 2 cases （18.2%）.9 cases （81.8%） were classified as stage Ⅰ-Ⅱ, 2 cases （18.2%） were classified as stage Ⅳ.Conclusion MSCT enhanced scanning can provide a reliable basis for the diagnosis and staging of gastrointestinal MALT lymphoma.The chest and abdominopelvic cavity enhanced scanning is recommended as a routine examination.
