  • Title: Pulmonary Opacities and Bronchiectasis Avid on 68Ga-PSMA PET.
    Author: Bouchelouche K, Vendelbo MH.
    Journal: Clin Nucl Med; 2017 Apr; 42(4):e216-e217. PubMed ID: 28134694.
    Abstract:
    Prostate-specific membrane antigen (PSMA) is highly expressed in prostate cancer, and the expression increases with tumor aggressiveness, metastatic disease, and recurrence. Despite its name, PSMA is also expressed in neovasculature of other tumors including lung cancer. Here, we demonstrate a case of increased PSMA expression on Ga-PSMA PET/CT in benign lung opacities and bronchiectasis in a prostate cancer patient. Thus, increased PSMA activity in the lungs may be due to both benign and malignant diseases and warrants further evaluation.
