After we performed the blinded evaluation of the 68Ga-PSMA-11 PET/CT in the present study, a number of cases with PSMA-avid bone uptake in benign skeletal conditions were published [18–21], revealing that fibrous dysplasia in the ribs or rib fractures may be PSMA-avid. The gene discussed is FOLH1; the disease is fibrous dysplasia.
