Figure 1. A 55-year-old woman with a history of breast cancer (invasive ductal carcinoma of the right breast, stage I) underwent a FDG-PET/CT scan due to elevated serum CA15-3 level of 44.7 U/ml.

FDG-PET/CT showed local recurrence in right anterior chest wall, extensive lymphatic invasion, and multiple metastases to liver, lungs and bones (SUVmax = 17.5, cross cursor). The patient's disease progressed rapidly, and she expired 8 months later. FDG-PET/CT, 2-[¹⁸F]fluoro-2-deoxy-Dglucose-positron emission tomography/computed tomography; SUV, standardized uptake value.
