目的 研究乳腺分叶状肿瘤(PTB)的超声表现以及与病理基础的关系,以提高超声的诊断水平.方法 回顾性分析经手术病理证实的58例PTB超声表现,其中17例经超声弹性成像检查,并将其与病理结果对照.结果 58例PTB中30例为良性,15例为交界性,13例为恶性.大于30 mm的肿块中,良性的比例比小于30 mm的肿块少.按超声图像分型,呈明显分叶状的实性肿块26例,呈浅分叶状或表现为圆形、椭圆形的实性肿块20例,呈囊实混合性的12例.良性与恶性,良性与交界性PTB的血流分级差异有统计学意义.结论 超声对PTB的诊断和鉴别诊断有重要的临床价值.%Objective To investigate the sonographic features and the relationship with the pathological basis of phyllode tumor of the breast,and improve the diagnostic level of ultrasound.Methods The ultrasono graphies of 58 pa-tients with pathologically proved PTB were analyzed retro spectively,among them 17 cases by ultrasound elasticity ima-ging,which were compared with pathological results.Results Thirty cases were benign,15 were borderline and 13 were malignant.Of the masses larger than 30mm,the benign ratio was less than the shorter cases.According to the ultrasound image types,there were 26 cases of solid mass with distinct lobules,20 cases of solid mass showed a shallow lobes or round,oval,and 12 cases were cystic hybridity.There was a statistical difference in the blood flow between benign and malignant or borderline PTB.Conclusion Ultrasonography has an important clinical value in the diagnosis and identify of PTB.
