中文摘要：

目的探讨乳腺叶状肿瘤的二维超声（2DUS）、CDFI及超声弹性成像（UE）特征。方法回顾性分析17例乳腺叶状肿瘤的2DUS、CDFI及UE表现。结果15例（15／17，88．24％）肿瘤边界较清晰；11例（11／17，64．71％）形态规则，表现为椭圆形或1～2个小分叶，6例（6／17，35．29％）形态不规则，表现为3个以上的明显分叶；8例（8／17，47．06％）肿瘤内部出现囊性变；血流Ⅱ级9例（9／17，52．94％）、Ⅲ级8例（8／17，47．06％）；UE评分3分4例（4／13，30．77％）、4分9例（9／13，69．23％）。结论超声提示明显分叶、囊性变、无微钙化、血流信号较丰富对乳腺叶状肿瘤的鉴别诊断有一定提示意义。

英文摘要：

Objective To assess the features of two-dimensional ultrasonography （2DUS）, CDFI and ultrasonic elastography （UE） for phyllodes tumor of the breast （PTB）. Methods 2DUS, CDFI and UE findings of 17 cases with single PTB were retrospectively analyzed, Results There were 15 masses （15/17, 88.24%） with clear boundary, 11 （11/17, 64.71）, oval or gently lobulated） with regular shapes, whereas 6 masses （6/17, 35.29%, obviously lobulated） with irregular shapes. Internal anechoic area was found in 8 masses （8/17, 47. 06 %）. Nine masses （9/17, 52.94 N） were detec- ted with level II vascularity, 8 （8/17, 47.06%） with level ]II vascularity. Among 13 patients underwent UE, 4 masses were scored of 3 （4/13, 30.77%）, 9 （9/13, 69.23~） were scored of 4. Conclusion Obvious lobulated shape, internal anechoic area, non-microcalcification and marked vascularity shown on ultrasonic images are helpful to differential diagnosis of PTB.
