Breast abscess. A 45-year-old woman presented with a palpable area in the right breast. Mediolateral oblique (a) mammogram shows a focal asymmetry in the upper outer breast (arrow) and associated trinagular palpable marker. Power Doppler ultrasound images (b, c) reveal two hypoechoic, oval masses with peripheral vascularity in the same region (asterisks). Axial post-contrast T1-weighted MRI (d), sagittal T2-weighted MRI (e), and postcontrast subtraction T1-weighted MRI (f) show two T2-hyperintense, rim-enhancing masses (arrows). Needle biopsy showed acute inflammatory cells consistent with abscess without evidence of malignancy
