A 45-year-old female patient with right breast lump. Mammography craniocaudal (a) and mediolateral oblique (b) views show focal asymmetry (arrow) in the right upper outer quadrant (BIRADS IV lesion). Axial TI contrast-enhanced fat-suppressed image on dynamic sequence (c) showed homogenous segmental non-mass enhancement (NME) (arrow) with well-defined enhanced intraductal lesion (arrow head). Axial MIP image (d) shows the right breast non-mass enhancement with increased vascularity to right breast. Dynamic time-intensity curve (e) shows type II “plateau” curve. The lesion elicits faint high signal intensity on DWI at b value = 400 (f) with a mean ADC value of 1.2 × 10–3 cm/s on ADC map (g). MRI findings: BIRADS IV lesion. Histopathological diagnosis: atypical ductal hyperplasia
