CT and [¹⁸F] FDG PET-CT scans of the breast mass. (A) Non-contrast axial CT scan reveals a large irregular mass in the right breast, and (B) [¹⁸F] FDG PET-CT reveals that the mass is metabolically active. (C) Non-contrast axial CT scan demonstrates tumor metastasis in the iliac region, and (D) [¹⁸F] FDG PET-CT demonstrates its metabolic activity. (E) Non-contrast axial CT scan shows bone destruction in the ischium with a surrounding soft tissue mass, and (F) [¹⁸F] FDG PET-CT demonstrates metabolic activity of the ischium and soft tissue mass. CT, computed tomography; [¹⁸F] FDG, fluorine-18 fluorodeoxyglucose; PET, positron emission tomography.
