Abstract: Objective To evaluate the imaging features of phyllodes tumor of the breast.Methods 35 patients with phyllodes tumor of the breast confirmed by surgery and histopathology were collected.All clinical and imaging findings were analyzed.Results 35 cases with 36 lesions were classified as benign (1 9 lesions),borderline (8 lesions),and malignant (9 lesions).The typical ap-pearances on mammography were ellipse (1 6/36)or lobulated (20/36)mass.Most of them were high density (30/36)and clear boundary (28/36).No evidence of calcification,spiculated margin,skin thickening,nipple retraction and enlargement of axillary lymph nodes were detected.On MRI,1 lesion presented as lobulated mass with nonuniform hypointensity on T1 WI,hyperintensity on T2 WI and DWI.The time-intensity curve was Ⅱ type on dynamic contrast enhancement MRI.Conclusion The clinical and ima-ging features of phyllodes tumor are characteristic.These features are helpful to preoperatively diagnose,the final diagnosis would confirmed by histopathology.
