Fig. 2

40-year-old female with history of left breast cancer managed by lumpectomy on follow-up mammogram and ultrasound revealed irregular lesion seen at lumpectomy site (BIRADS 4a). CE-MRI breast (a, b) axial T1 and axial STIR showed irregular isointense lesion with central fat signal (red arrow). c Dynamic THRIVE images showed enhancing irregular lesion with suppressed central areas of fat (red arrow), showing type I curve of dynamic enhancement. d DWI showed no restricted diffusion (ADC = 1.9 × 10−3 mm2/s). e FA map, FA = 0.18 (< 0.2) matching with the benignity of the lesion. Final MRI diagnosis was fat necrosis at site of lumpectomy (BIRADS 3), which was confirmed later by clinical and imaging follow-up
