A Case of Brown Tumor on 68Ga-DOTATATE PET/CT and 18F-FDG PET/CT

A 50-year-old man presented with right chest pain and persistent increased parathyroid hormone after parathyroidectomy for parathyroid carcinoma. Ga-68-DOTATATE PET/CT and F-18-FDG PET/CT were performed consecutively for restaging to determine subsequent treatment strategy. An osteolytic lesion on the right sixth rib showed increased uptake on both Ga-68-DOTATATE and F-18-FDG PET/CT. Subsequent biopsy confirmed it to be a brown tumor.
