摘要 目的分析64排螺旋CT对胃淋巴瘤的CT征象特点,并探讨其对该病的诊断价值。方法回顾性分析21例经胃镜活检或手术切除病理证实淋巴瘤的64层螺旋CT表现。结果本组21例患者均为非霍奇金氏淋巴瘤。病变部位:3例胃窦,5例胃体,9例累及两个及以上部位,4例为弥漫浸润,同时累及两个及以上部位的占61.90%;胃壁呈不均匀增厚,厚度范围为1.3~5.4 cm,均数3.4 cm,其中9.52%呈局限性增厚,4.29%呈节段性增厚,76.19%呈弥漫性增厚,2例显示深溃疡形成,1例胃黏膜呈"梳齿征"。增强扫描病灶呈中度强化。95.24%病灶显示胃腔形态可改变。80.95%病灶胃周围脂肪间隙清晰。结论胃淋巴瘤的CT表现具有一定的特征性,多个部位或弥漫性胃壁不均匀增厚,黏膜皱襞结节样增厚,胃周脂肪间隙清晰,胃壁有一定扩张度和柔软度时高度提示胃淋巴瘤可能。
