Abstract： 目的探讨原发性小肠恶性淋巴瘤的CT诊断价值.方法 11例均行CT平扫,8例加做增强扫描,扫描层厚、层距均为10 mm.结果 11例肿瘤,发病部位以回肠最常见,占10例.肠壁环形增厚型7例,其中5例见肠腔呈动脉瘤样扩张;肠腔内息肉样肿块型4例,3例继发肠套叠.该2型同时伴有肠系膜淋巴结多发肿大7例,其中1例见"夹心面包征”;受累肠段显著较长或呈多发节段性分布4例.CT初诊肿瘤检出9例,定性诊断准确7例.结论肠壁增厚型和肠腔内息肉样肿块型是小肠原发性淋巴瘤的2种主要CT表现类型.伴有肠系膜淋巴结多发肿大的肠壁增厚或肠腔内分叶状肿块、"动脉瘤样肠腔扩张征”、"夹心面包征”、受累肠段较长及呈多发节段性分布是小肠原发性淋巴瘤的主要特征性CT表现,具有较可靠的定性诊断价值.
