Female patient aged 42 years old presented by palpable left breast mass. A Axial early subtraction MR image shows irregular shaped soft tissue mass with speculated margin and heterogeneous enhancement within the lower outer quadrant of the left breast. B, C Axial DWI and ADC show high SI in DWI and low SI on ADC map (restricted diffusion) with mean ADC value = 0.32 × 10–3 mm2/s. D Axial DTI image shows FA value 0.18. E, F Time intensity curve shows Type III curve (wash out curve) with maximum enhancement 2248.6, Time to peak 137.2swith wash out ratio 1.5 s. G Pathological diagnosis was grade III invasive ductal carcinoma luminal B her2 positive (ER and PR positive with high Ki-67 index (Ki-67 = 80%) and HER2-positive)
