Metaplastic breast carcinoma is a rare type of neoplasms with mixed epithelial and mesenchymal differentiation. Metaplastic carcinoma with chondroid differentiation is relatively an uncommon type among the different types of metaplastic carcinoma. In this report we present a case of metaplastic breast carcinoma with chondroid differentiation as a complex mass containing both components of invasive ductal carcinoma and chondroid differentiation. The invasive ductal carcinoma and chondroid differentiation show early contrast enhancement, delayed contrast wash out, diffusion restriction and intermediate or high signal intensity on T2-weighted image with minimal contrast enhancement, respectively.
