MR images: a T2. b STIR. c DCE-MRI post-contrast. d DCE-MRI subtraction images. A large right upper outer quadrant (UOQ) irregular mass with a speculated margin is seen eliciting intermediate T2 and high STIR signal intensity “arrow” with multiple foci surrounding the lesion are also seen displaying intermediate T2 and bright STIR signal intensity “arrowheads.” On dynamic post-contrast images the enhancing mass “arrow” and the multiple peri-lesional foci all show rim enhancement “arrowheads” The pathology revealed TN invasive ductal carcinoma
