A T1-WI: a well circumscribed rounded shape mass with smooth margins at the UOQ of low signal intensity. B T2-WI: the mass shows intermediate signal intensity (SI) with a central high intra-tumor signal intensity. C and D Dynamic and subtraction post contrast MRI: the smooth margin and the rounded shape are more evident. The mass shows thick rim enhancement. E TIC: the mass shows type III TIC (washout). F DWI (at b = 1000): the lesion shows peripheral high signal intensity and low central signal intensity. G Grayscale ADC map: the lesion shows restricted diffusion and calculated ADC mean values: 0.8 X10 − 3 mm2 /s. Final molecular diagnosis: Triple negative breast cancer. BIRADS (MRI-Lexicon):4, BIRADS (Kaiser Score): 5
