Prostate-specific membrane antigen (PSMA) is a specific type II membrane glycoprotein. We present the case of a 72-year-old man with newly diagnosed prostate cancer who had a 68 Ga-PSMA PET/CT scan for staging.68 Ga-PSMA PET/CT images showed moderate uptake in the right hemithorax,corresponding to pleural thickening seen on the CT images. Histopathologic examination revealed the diagnosis of chronic inflammation. It is important to keep in mind other alternative diagnoses such as chronic inflammation when 68 Ga-PSMA PET/CT identifies uptake at an atypical site.
