FIGURE 1:

a: A 48-year-old woman (Table 1, No. 9) with screen mammography detected grouped coarse heterogeneous and linear calcifications (BIRADS 4c) in the left upper outer quadrant (arrow). b: The stereotactic biopsy with 9G core needle was performed for the calcifications and seven core samples were obtained. The pathologic result was a single focus of atypical ductal hyperplasia (ADH). Postbiopsy mammogram showed multiple residual calcifications besides biopsy clip. c: Axial T1-weighted contrast-enhanced subtracted MR image 48 days after biopsy showed clip artifact within 11 mm focal heterogeneous nonmass enhancement (NME) with rapid plateau kinetics. The retro-pectoral implant was also observed (arrow). Surgical pathology showed scattered foci of ductal carcinoma in situ (DCIS) intermediate grade. The MRI finding is true-positive.
