Figure 23c. Recurrent metastatic disease in a 33-year-old woman with invasive ductal carcinoma of the right breast, which was treated with surgical resection and dissection of the left axillary nodes. FDG PET-CT was performed to evaluate for recurrence. (a) Axial CT image shows a small lymph node in the right axilla (arrow). (b) Corresponding fused FDG PET-CT image shows mild hypermetabolism in the node (arrow), which represents recurrent metastatic disease. (c) Coronal fused FDG PET-CT image shows intense hypermetabolism in the left humeral head (arrow), which represents recurrent metastatic disease.
