MRI and pathology findings of a mass-like fat necrosis in the breast

Abstract

Fat necrosis of the breast is a benign inflammatory process and, it has a wide range of findings on Magnetic Resonance Imaging (MRI), some of which are in the malignant spectrum. We present a case of a breast fat necrosis that mimicked malignancies on MRI because of the intense internal enhancement with a type 3 kinetic curve, its relatively large size, and axillary lymphadenopathy.
