A 42-year-old female patient with breast lump in the upper outer quadrant of the right breast. Mammography craniocaudal (a) and mediolateral obliquel (b) views show focal asymmetry in the right upper outer quadrant, associated with pleomorphic microcalcifications (BIRADS IV lesion). Axial TI contrast-enhanced fat-suppressed image on dynamic sequence shows an intensely enhancing irregular right breast mass (arrow) surrounded by segmental area of increased parynchemal enhancement (c). Another smaller enhanced well-defined regular mass (D) seen posteroinferiorly (arrow) to the previous mass, suggesting multicentric carcinoma. Dynamic time-intensity curve (e) shows type II “plateau” curve. The lesion shows hyperintense signal in DWI (f) denoting restricted diffusion, and low signal on ADC map (g) with measured ADC value 0.56 × 10–3 mm2/s. Restricted diffusion of the ipsilateral axillary lymph nodes (h) with low ADC value 0.67 × 10–3 mm2/s. MRI findings: BIRADS V lesion. Histopathological diagnosis: Invasive ductal carcinoma
