Comparison of Contrast-Enhanced Spectral Mammography and Contrast-Enhanced MRI in Screening Multifocal and Multicentric Lesions in Breast Cancer Patients

Figure 2

Imaging features of a 39-year-old woman with MMBC in the right breast. (a) CC position in the right breast. In CESM, the LE-MG imaging indicated a star-shaped mass in the outer quadrant of the right breast (arrow). (b) In CESM, the RSM imaging indicated six slightly enhanced masses with irregular edges and not circumscribed margin (arrows). (c) Enlarged LE-MG imaging: there were clusters of fine linear branching calcifications. Combined with the RSM imaging, the six small masses were diagnosed as BI-RADS 5. (d) US indicated only two hypoechoic masses with irregular edges (crosses), which was classified as BI-RADS 4A. Six masses were confirmed as IDC after surgery. (e) The pathology features of HE under a magnification of 20×. (f) The smallest mass was DCIS with a diameter of 3 mm. The HE staining results were observed under a magnification of 10×.
