Table 1.
Clincal characteristics of breast cancer and inflammatory breast diseases.
Figure 1.
A 50 year-old woman in the breast cancer group.
A painful mass was found in the right breast for 2 weeks. Pathology: invasive ductal carcinoma. T1-weighted contrast-enhanced MRI (108 s) reveals a rim-enhanced mass with a thin wall, an irregular shape and a spiculated margin.
Figure 2.
A 44 year-old woman in the inflammatory breast diseases group.
A painful mass was found in the right breast for 3 days. Pathology: inflamed dilated ducts with cyst formation. T1-weighted contrast-enhanced MRI (108 s) reveals a rim-enhanced mass with a thin wall, an oval shape, internal septa (arrowhead), and a smooth margin.

Figure 3.
A 26 year-old woman in the breast cancer group.
A painful mass was found in the right breast for 2 months. Pathology: invasive ductal carcinoma. A. T1-weighted contrast-enhanced MRI (108 s) reveals a rim-enhanced mass with a thick wall and smooth margin. B. STIR indicates the prepectoral edema (arrows) and partial of the non-enhancing central part corresponding to contrast-enhanced MRI presents as hyperintensity. C. The mass shows peripheral hyperintensity on DWI. D. The corresponding ADC map shows the ADC value of the wall is 1.04×10−3 mm2/s, the central part, 2.70×10−3 mm2/s.
Figure 4.
A 27 year-old woman in the inflammatory breast diseases group.
A painful mass was found in the left breast for 1 month during breastfeeding. Pathology: lactating abscess. A. T1-weighted contrast-enhanced MRI (108 s) reveals a rim-enhanced mass with irregular margin. B. STIR indicates no prepectoral edema and the non-enhancing central part corresponding to contrast-enhanced MRI presents as hyperintensity. C. The mass shows central hyperintensity on DWI. D. The corresponding ADC map shows the ADC value of the wall is 1.33×10−3 mm2/s, the central part, 0.861×10−3 mm2/s.
