Magnetic resonance imaging showed five heterogeneously enhanced masses, 5.8-cm-diameter at a maximum, in the right breast, and six enhanced masses, approximately 1–3 cm in diameter, in the left breast (arrows in a). These masses showed high intensity on fat-suppressed T2-weighted images (b). The contrast-enhanced images exhibited heterogeneous enhancement in the early phase (c), and progressive and concentric enhancement in the delayed phase (d). N: nipple
