Fig. 1. 56-year-old female with IDC in right breast and thymoma.

A. CE T1-weighted-MRI shows a 1.4 cm in size IDC in the right breast (arrow).

B. CE T1-weighted-MRI shows an enhancing mass in the anterior mediastinum (arrow).

C. In the axial chest CT, there is an enhancing nodule at the same location as the MRI (arrow).

D. PET/CT shows a round-shape mass with fluorodeoxyglucose uptake (max SUV 2.3) in the same location as the MRI (arrow). The mass was diagnosed as a thymoma after excision and biopsy.

CE = contrast-enhanced, IDC = invasive ductal carcinoma, max SUV = maximum standardized uptake value
