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 high-grade MALT lymphoma 2 cases(28.5%),in which ulcers(n=4), fold thickening and mucosal nodules (n=1), orprominent 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.%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MALT 5例(71.4%),高级别MALT 2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.
