Example of MRI findings of breast lesions categorized as BIRADS 4A by previous echography. A 27-year-old patient with a family history of breast cancer in mother and grandmother. Above: T1-W axial (a), T2 VISTA axial (b) and ADC map (c) show a heterogeneous mass with a solid component in the periphery and a hyperintense central area due to a fatty component, no restricted diffusivity with an ADC of 1.9 × 10⁻³mm²/s. Bottom: initial (d) and delayed (e) postcontrast subtractions, and the wash-in map (f) show a progressive uptake of contrast. Morphological and kinetic features are compatible with hamartoma reported in previous echography. It was assigned as the BIRADS-2 category
