乳腺叶状肿瘤的超声特征与病理结果对比分析

Comparative analysis between ultrasonic characteristics and pathology of phyllodes tumors of the breast

目的探讨不同病理类型的乳腺叶状肿瘤(PTB)的超声声像图特征。方法回顾分析16例PTB二维及彩色多普勒超声声像图表现。结果按WHO分类标准,16例PTB分为良性12例、交界性(低度恶性)2例、恶性2例;其中7例伴发乳腺纤维腺瘤,包括6例良性、1例交界性PTB。PTB声像图均表现为边界清晰。良性PTB声像图表现为形态规则或欠规则,内部回声均匀或不均匀,少部分后方回声增强。交界性及恶性PTB声像图表现为形态规则、不规则或欠规则,内部呈囊实性回声或回声不均匀,后方回声增强。16例PTB均未见钙化。结论不同病理类型的PTB声像图有一定特征,认识这些特征有助于PTB的鉴别诊断。

Objective To investigate the ultrasonic features of phyllodes tumors of the breast（PTB） with different pathologic types.Methods Two-dimensional ultrasound and CDFI were performed in 16 patients with pathologically proved PTB,and the ultrasonic characteristics of different pathologic types PTB were reviewed retrospectively.Results According to WHO criteria,there were 12 benign PTB,2 borderline and 2 malignant PTB.Associated breast fibroadenoma was detected in 7 patients,including 6 benign and 1 borderline PTB.All of 16 PTB had clear boundary.Benign PTB had regular or irregular shapes,homogeneous or unhomogeneous internal echo and posterior acoustic enhancement in a few cases.Most borderline and malignant PTB showed regular or irregular shapes,mixed cystic and solid internal echo or irregular internal echo,as well as posterior acoustic enhancement.No calcification of PTB was found in all 16 patients.Conclusion The ultrasonograghic features of PTB with different pathologic types are characteristic to some extent,therefore being helpful to the differential diagnosis of PTB.
