A 42-year-old woman with a luminal A-like carcinoma in the outer upper quadrant of the left breast. a Axial diffusion-weighted image (b-value = 1,000 s/mm.2) shows the high signal intensity of the mass, corresponding to a restricted diffusion area. b Axial post-contrast T1-weighted subtracted image shows a 14-mm mass with irregular shape, spiculated margins, and heterogeneous enhancement. c On cut surface, the lesion has irregular and infiltrative borders. d–e Histologic examination confirms the diagnosis of infiltrating carcinoma of “no special type” with diffuse expression of oestrogen receptor on immunohistochemistry
