Abstract

Positron emission tomography (PET) with fluorine‑18‑labeled fluorodeoxyglucose (18F‑FDG) has been used for the staging and evaluation of recurrence in cancer patients. We herein report a false‑positive result of 18F‑FDG PET̸computed tomography (CT) scan in a patient following chondrosarcoma resection and metallic implanting. A 35‑year‑old male patient with chondrosarcoma of the left iliac bone underwent radical resection, metal brace implanting and radiotherapy. A high uptake of 18F‑FDG was observed in the metallic implants and adjacent tissue during PET/CT scanning in the 5th year of follow‑up. tissue biopsy and follow‑up examination identified no tumor recurrence or infection at these sites, suggesting that the results of 18F‑FDG PET̸CT must be interpreted with caution in cancer patients with metallic implants.
