59 year-old patient with mastitis carcinomatosa (inflammatory carcinoma), finally diagnosed as ductolobular carcinoma with a ≥ 95% proportion of the lobular component. a) Craniocaudal and mediolateral mammograms show extensive skin and trabecular thickening/coarsening of the right breast and diffusely increased breast density, associated with multiple calcifications in the upper outer breast. b) MRI shows multiple confluent masses, with irregular margins and heterogeneous internal enhancement pattern. Skin thickening and invasion of the nipple and the pectoral muscle are also observed. These are the typical features of inflammatory carcinoma. Multicentricity (multifocal and multicentric disease simultaneously) can also be observed in coronal projection (c). d and e) Post-processed color parametric map image demonstrates multiple areas of malignant enhancement in axial projection. Kinetic curve demonstrates typical malignant pattern (rapid initial rise and washout).
