摘要 目的分析乳腺叶状肿瘤(PTB)的影像学表现。方法收集经手术病理证实的PTB 16例,其中12例行乳腺X线钼靶检查,3例行MRI扫描,1例行CT扫描,回顾性分析PTB的影像。结果 16例肿瘤中,13例为分叶状,3例呈类圆形;肿瘤平均长径(7.8±4.6)cm,2例交界性体积最大;11例累及2个或2个以上象限,以外上、内上象限受累多见。12例PTB X线钼靶检查肿瘤均为高密度,边界清楚,11例伴晕征,8例见多轮廓征。3例PTB MRI平扫T1WI为等或低信号,T2WI主要为高信号,内见囊变、分隔及增粗血管,MRI动态增强扫描均为渐进性强化。1例交界性PTB CT平扫为等低密度,边界不清,增强扫描不均匀强化,内见囊变及增粗血管影。结论 PTB影像学表现有一定特征,结合临床特点,可提高该病的术前诊断。
