Comparative analysis between ultrasonic characteristics and pathology of phyllodes tumors of the breast / 中国介入影像与治疗学

ABSTRACT

ObjectiveTo investigate the ultrasonic features of phyllodes tumors of the breast (PTB) with different pathologic types.MethodsTwo-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.ResultsAccording 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.
