Images in a 49-year-old patient originally treated for hormone receptor-positive invasive cancer without preoperative MRI who developed bloody nipple discharge two years after surgery. (A) Left mediolateral oblique mammogram shows new grouped pleomorphic calcification (arrow) adjacent to the previous operation site. (B) Transverse ultrasound image shows a 2.3-cm hypoechoic mass (arrows) with calcifications. (C) Axial contrast-enhanced fat-saturated T1-weighted MRI scan shows an irregular, heterogeneously enhancing mass (arrow) in the left breast, adjacent to the operation site. The final pathologic examination confirmed recurrent invasive ductal carcinoma.
