F18-FDG PET/CT study (a) maximum intensity projection showing intensely FDG-avid soft tissue mass in the right breast tissue, FDG avid cervical, right supraclavicular, right axillary, mediastinal and abdominal lymph nodes. Intense FDG uptake (arrow) in the region of right atrium is also noticed. Transaxial-fused PET/CT image (c) showed intensely FDG avid right atrial lesion (arrow) and soft tissue density in the right breast. Repeat PET/CT scan (b) after 2 cycles of chemotherapy showing complete resolution of FDG avidity in the breast, heart and bone lesions. Mild FDG uptake is noted in a few cervical and right axillary lymph nodes suggestive of significant metabolic response. Transaxial-fused PET/CT image after two cycles of chemotherapy (d) also showed complete resolution of FDG avidity in the breast and heart

D12-L2 vertebral bodies. Thyroid scan showed cold nodule in the right lobe of thyroid gland. Due to indeterminate nature of the lesions, F18-FDG PET/CT was performed [Figure 1].
