Figure 4. Dynamic MRI of the treatment area at 3 months and 6 months, before and 1 min, 2 min, 3 min, 4 min and 6 min after intravenous gadolinium. Note the three distinct areas of the breast: the nipple area enhances early; the 50 mmx70 mm central fat necrosis does not enhance at all; the peripheral area (area 2) abnormally. 3 months later, an air–fluid level developed within the fat necrosis, the hypervascular margin was proved to be the granuloma located at the periphery of the pyogenic abscess.
