Computed tomography (CT) revealed a large mass measuring 10 cm x 10 cm in the lower region of the left breast, with pleural and skin thickening and fracture of the fifth rib under the mass (Figure 3(a)). Contrast-enhanced T1-weighted magnetic resonance imaging with fat suppression revealed a low-signal intensity mass in the lower region of the left mammary gland, and contrast enhancement revealed its border and the adjacent pleura (Figure 3(b)).
Computed tomography showing that the abscess cavity has shrunk and that the fracture in the fifth rib has healed (arrow).
