摘　　要：目的探讨原发胃淋巴瘤的X线气钡双重造影表现和组织病理类型之间的相关性。方法回顾经病理证实的7例原发胃淋巴瘤的X线气钡双重造影表现,分析溃疡、黏膜增粗紊乱及粗大皱襞、肿块、弥漫浸润或多发结节与病理类型低级别淋巴瘤、高级别淋巴瘤的关系。结果7例中低级别MALT5例(71.4%),高级别MALT2例(28.5%),X线气钡双重造影,溃疡4例,黏膜增粗紊乱及粗大皱襞型1例,胃体3例(42.8%),胃窦2例(28.5%),胃底2例(28.5%)。结论不同组织病理类型胃黏膜相关淋巴瘤表现多种多样,溃疡、小结节状突起是低级别淋巴瘤常见征像,高级别淋巴瘤多以肿块出现。与胃癌很难鉴别.Objective To investigate the radiological findings of double-contrast gastrointestinal examination with pathologic correlation. Methods The radiological features of double-contrast gastrointestinal examination, including ulcers, fold thickening ,mucosal nodules, and masses, in 7 cases with clinicopathlogically-proved MALT lymphoma were retrospectively analyzed, and to find out the radiological features correlate with different pathological classification of gastric MALT lymphoma such as low-grade MALT and high- grade MALT. Results In 7 cases of gastric MALT lymphoma, 5 cases with low-grade MALT lymphoma（71.4%）, 2 cases with highgrade MALT lymphoma 2 cases（28.5%）,in which ulcers（n=4）, fold thickening and mucosal nodules （n=1）, or prominent area gastricae （n= 2） at the examination. Three patients （42.8%） had lesions in the gastric body. Two（28.5%） had lesions in the antrum, and two （28.5%） had lesions in the fundus. Conclusion gastric MALT lymphoma with different Histopathology has multiplex radiological findings.But ulcer, multiple nodules in low-grade MALT lymphoma is common and masses is common in high-grade MALT lymphoma, however, which is unpleasant distinguish with gastric carcinoma.
