RESUMO
Fibrous dysplasia (FD) is a benign bone lesion with a rare but potential for malignant transformation. Neither Tc-MDP nor F-FDG PET/CT can differentiate between FD and areas of malignant transformation in FD. We described a case of osteosarcoma developing in FD with selective uptake of tracer in malignant transformation areas demonstrated on a Ga-PSMA PET/CT scan. Our case highlights the ability of Ga-PSMA PET/CT to map tumor neoangiogenesis in osteosarcoma arising in FD, which can have potential implications in prognostication, possibility of antiangiogenesis-based therapeutic options, and in response assessment following chemotherapy.
