目的：探讨胃原发性淋巴瘤的影像诊断问题。方法：对１０年间所确诊的２０例胃淋巴瘤的钡餐及ＣＴ资料进行回顾性分析。结果：病变范围广泛，多累及胃的二个以上区域；肿块呈单发，多发结节或溃疡，边缘轮廓光滑；粘膜皱襞粗大，形态固定而完整；胃壁增厚，扩张度好。结论：钡餐结合ＣＴ检查对胃淋巴瘤与胃癌鉴别诊断有重要价值。结合临床可提高确诊率。
Objective: To investigate the imaging diagnosis of primary gastric lymphoma. Methods: The barium meal and CT data of 20 cases of gastric lymphoma diagnosed in 10 years were retrospectively analyzed. RESULTS: The lesions were extensive and affected more than two regions of the stomach. The masses were single, multiple nodules or ulcers, and the contours of the lesions were smooth. The mucous membranes were thick, with a fixed and complete shape. The stomach wall was thick and well dilated. Conclusion: Barium meal combined with CT examination has important value in differential diagnosis of gastric lymphoma and gastric cancer. Combined with the clinical can improve the diagnosis rate.
