    ABSTRACT: We report 2 separate cases with significant head motion causing apparent hypometabolic and hypermetabolic cerebral activity on FDG PET/CT. Case 1 is a 57-year-old man with facial numbness status post chemotherapy for mantle cell lymphoma. Restaging attenuation-corrected PET showed increased left frontal region activity, whereas nonattenuation-corrected PET demonstrated evidence of patient motion with normal physiologic left frontal cortical activity. Case 2 is a 78-year-old man with history of malignant melanoma. Attenuation-corrected PET/CT demonstrated diffusely decreased activity in the left cerebral hemisphere, whereas nonattenuation-corrected PET showed significant head motion with intact cortical activity.

    ABSTRACT: We present 4 cases of cosmetic-related changes on 18F-FDG PET/CT. These cases represent post-treatment changes from facial juvederm injection, silicone injection in the chest wall and gluteal areas, paraffin injection in the gluteal region, and liposuction. Recognition of cosmetic-related changes and their appearance on PET and CT will help to avoid potential false-positive interpretations.
