Zhongshan Daxue xuebao. Yixue kexue ban, 2008 目的】 总结胃淋巴瘤的CT表现特征，以提高CT对胃淋巴瘤的诊断价值。【方法】 回顾性分析经病理证实的25例胃淋巴瘤的CT表现，包括胃受累的部位、病灶大体形态、侵犯范围、胃壁厚度、浆膜及胃周脂肪间隙受累情况、强化方式、坏死、其他器官受累、淋巴结肿大情况，并将CT征象与病理类型进行对照分析。【结果】 本组25例胃淋巴瘤病人，均为非霍奇金氏淋巴瘤。大多数发生在胃窦（18/25，72％）和胃体（19/25，76％）。胃壁不均匀增厚，最厚处胃壁厚度为7 mm ～ 60 mm，平均（21．3 ± 12．9） mm ...
