2、方法回顾性分析经病理证实的22例ACC的CT与MRI表现,并与病理结果进行对照研究。结果22例患者中,发生于腮腺7例、上颌窦3例、舌3例、下颌下腺3例、鼻腔2例、筛窦2例、腭1例、气管1例,形态较规则14例,不规则形8例;直径10mm53mm,平均约29mm;14例行CT检查,平扫5例为均匀等、稍低密度,9例为不均匀等低密度,增强扫描4例均匀强化,10例不均匀强化,内见小斑片状、筛孔状未强化区。8例行MRI检查,T1WI为均匀或不均匀等、低信号,T2WI主要为混杂高信号,6例内见小斑片状、筛孔状更高信号区,增强扫描2例均匀强化,6例不
3、均匀强化,内见小斑片状、筛孔状未强化区。周围结构侵犯9例,淋巴结转移3例,远处转移1例。结论ACC的病理基础决定其影像表现,CT及MRI增强扫描ACC易出现小斑片状、筛孔状未强化区域,并且CT与MRI检查对判断肿瘤侵犯范围起重要作用。关键词：腺样囊性癌;磁共振成象;体层摄影,X线计算机;病理学;收稿日期：2017-09-26TheCTandMRIFindingsandPathologicalBasisofAdenoidCysticCarcinomaoftheSalivaryGlandsLIUZao-songYEYaoWEIXin-hu
