Breast magnetic resonance imaging (MRI). (a) T1-weighted MRI showed a low signal intensity (SI) mass (3.5 × 3.2 × 4.0 cm in size) that retracted the right nipple. Several oval-shaped low SI structures in adipose tissue and disruption of the pectoralis major muscle were also observed (arrows). (b) The mass showed intermingled high and low SI on T2-weighted images. (c, d) Heterogeneous early enhancement with central low intensity was noted on dynamic contrast-enhanced MRI (c: early phase, d: delay phase).
