| 摘 要： | 目的探讨腮腺腺淋巴瘤(Warthin瘤)的CT及MRI表现,旨在提高对本病的认识。资料与方法回顾性分析经手术病理证实的14例腮腺淋巴瘤的CT和MRI表现。12例行CT平扫,其中10例行增强扫描;2例行MRI平扫,其中1例行增强扫描。结果 14例共22个病灶,单侧多发3例,单侧单发9例,双侧单发2例且其中1例为术后14年对侧再发。16个(72.7%)病灶或病灶主体位于腮腺浅叶后下极,长径0.8～5.0cm,平均长径(2.3±1.3)cm,病灶呈圆形或卵圆形;19个(86.4%)病灶边缘光整,3例单发病灶边缘模糊,手术证实合并感染。12例(共18个病灶)CT平扫14个(77.8%)病灶密度均匀,4个(22.2%)病灶密度不均匀;10例(共15个病灶)增强扫描7个(46.7%)病灶呈明显强化,5个(33.3%)病灶呈中度强化,3个(20%)病灶呈轻度强化。3个病灶可见边缘线样强化。MRI上肿瘤呈均匀或不均匀信号,T1WI呈低信号,T2WI呈中等或高信号;平扫包膜呈环状低信号,增强扫描呈轻度强化。结论中老年男性,病灶位于腮腺后下极,边缘清晰,明显强化,特别是双侧或多发病灶,并有吸烟史者,应首先考虑腮腺腺淋巴瘤的诊断。
