68Ga-PSMA-HBED-CC PET/CT and 18F-FDG PET/CT in Ewing Sarcoma

Abstract We present a case of a 19-year-old woman with Ewing sarcoma of the iliac bone in whom 68 Ga-PSMA-HBED-CC PET/CT showed high radiotracer activity in the primary tumor. The present case documents the in vivo expression of PSMA in Ewing sarcoma family of tumors and adds on to the list of nonprostatic malignancies showing PSMA expression.
