摘要 目的提高对腮腺腺淋巴瘤MRI表现的认识。方法对手术病理证实的18例腮腺腺淋巴瘤的术前MRI图像进行回顾性分析。结果 18例腮腺腺淋巴瘤患者中男15例,女3例,平均年龄约为52岁,12例(约66.7%)表现腮腺单侧浅叶下部单发小结节样病变,2例(约11.1%)表现为腮腺单侧浅叶2~4个病变病,4例(约22.2%)表现为双侧腮腺多个病变;MRI扫描17例病变边缘清晰,16例病变T1WI呈不均匀低信号,脂肪抑制T2WI呈不均匀高信号,增强扫描病变动脉早期即呈轻-中度不均匀强化,静脉期强化减弱,病变内可见小囊状未强化影。结论腮腺腺淋巴瘤好发于中老年男性,可多发或双侧发病,边缘清晰,MRI扫描多为类圆形不均匀长T1、长T2信号影,动态增强扫描病变呈快进、快出表现。
