A case of pathologically proven multicentric IDC with major DCIS component IDC grade II (T2) sentinel lymph node status 1/5(N1). a Mammography showed no spiculated mass lesions or microcalcific clusters. Complementary ultrasound showed b right periareolar 8 o’clock ill-defined hypoechoic mass with increased vascularity and c right pathologically enlarged axillary lymph node. d, e DCE-MRI breast revealed a spiculated heterogeneously enhancing mass at 8 o’clock in the LOQ. The mass is seen reaching the nipple, associated multiple right breast central and lower quadrants similar enhancing nodules are seen. Lower outer quadrant regional pathological non mass enhancement is seen as well. f DWIs showed restricted diffusion. In this case, breast U/S and DWI-MRI detected a single lesion, while DCE-MRI was able to detect multicentricity of the lesions and correlated the best with the pathological specimen results
