Purpose To investigate the imaging features of breast phyllodes tumor on mammography(MG),ultrasound(US) and pathology, correlated with its clinical manifestation.Materials and Methods Twelve cases of pathologically confirmed breast phyllodes tumors were examined by US and MG. The imaging findings were retrospectively analyzed. Results Of the 12 cases of breast phyllodes tumors, 6 were benign, 3 were malignant and 3 were borderline. MG predicted 3 breast phyllodes tumors, 3 breast carcinomas and 6 adenomas. US predicted 2 phyllodes tumors, 8 breast masses and 2 adenomas. Conclusion The imaging findings of phyllodes tumors on MG and US are characteristic but not specific. Combined application of both US and MG are helpful for early detection but can not differentiate its malignancy which is determined by pathology.
