FIGURE 3:

a: A 52-year-old woman (Table 1, No. 15) with new focal asymmetry (BIRADS 4b) in the left lower outer quadrant at screening mammography (arrow). b: A targeted ultrasound showed an irregular hypoechoic mass with indistinct margins measuring 12 × 7 × 6 mm with minimal vascularity at the 6 o’clock position (arrow). c: The ultrasound-guided biopsy with 14G core needle (arrows) was performed for the lesion and three core samples were obtained. The pathology result was a single focus of ADH. d: Axial T1-weighted contrast-enhanced subtracted MR image 16 days after biopsy showed clip artifact within 12 mm focal homogeneous NME with rapid washout kinetics (arrow). Surgical pathology showed focal ADH with intraductal papilloma. The MRI finding is a false-positive.
