33-year-old female presented with recurrent mastalgia and left nipple brownish discharge. a CC and MLO mammogram views showed focal asymmetry of left LIQ (arrow). b Ultrasound showed dilated ducts at left LIQ showing echogenic content with no solid intra ductal lesion. c Axial STIR showed focal hyper intense signal at left LIQ reflecting focal edema (arrows). d Dynamic THRIVE images showed dilated ducts showing enhancing thickened wall (black arrows) with non-mass clustered ring enhancement (white arrow). e Type II curve of dynamic enhancement. f DWI showed restricted diffusion, ADC = 0.9 × 10−3 mm2/s. g FA value 0.11 (< 0.2) matching with benign lesion, MRI final diagnosis was focal mastitis (BIRADS 4a). h TCNB revealed granulomatous mastitis showing multinucleated giant cells (arrows) surrounded by chronic inflammation and fibrosis (H&E × 100)
