Department of Radiology

Phyllodes tumour is an uncommon fibro epithelial tumour of breast that often presents clinically as a rapidly enlarging lump. On mammography it appears as a soft tissue density well circumscribed mass. Ultrasound shows it to be a solid hypoechoic mass with small cystic spaces. A case of malignant phyllodes tumour with an atypical appearance of intracystic tumour on sonography is reported with pertinent imaging features and histopathological diagnostic criteria. The tumour had undergone osteosarcomatous differentiation.
