A T1-WI: a large retroareolar area of abnormal intermediate signal intensity reaching the nipple. B T2-WI: this area shows relatively high signal intensity associated with subcutaneous and perilesional streaks of high SI denoting edema. C and D Dynamic and subtraction post contrast MRI: the area is seen as an abnormal non-mass enhancement reaching the nipple and skin demonstrating heterogeneous pattern and segmental distribution. E TIC: exhibiting type III washout curve. F DWI at b = 1000: the lesion shows high signal intensity. G Axial grayscale ADC map: showing the lesion with restricted diffusion and mean ADC value: 0.8 X10 − 3 mm2 /s. Final molecular diagnosis: Her2neu subtype. BIRADS (MRI-Lexicon):4, BIRADS (Kaiser Score): 5
