18F-FDG PET-CT Scans in Oncology Patients Treated with Hyaluronic Acid Filler: Not Always a Pitfall

Figure 1

(a) 18F-FDG PET/CT: surface rendering (SR) of the skull (upper row) and corresponding fused axial PET/CT of the zygomatic region (lower row) before filler implant. (b) 18F-FDG PET/CT acquired during follow-up and after filler injection: SR of the skull (upper row) and fused axial PET/CT of the zygomatic region: no abnormal uptake, as a biomarker of inflammation, is evident with respect to the previous scan.
