MRI of breast showed a a circumscribed irregular T1 hypointense, b T2/STIR hyperintense lesion in upper outer quadrant at 10–11 o’clock position, closely abutting the skin (white arrows) with associated overlaying skin thickening. cLesion shows DWI restriction. d On maximum-intensity projection images, large feeding vessels arise (white arrow head) from internal mammary artery (white arrow). e T1 sagittal contrast shows homogenously enhancing lesion in the upper quadrant. f T1 contrast early phase shows contrast uptake. g, h Enhancement progresses to intense heterogeneous enhancement in later phases
