Case report demonstrates PSMA PET-CT imaging revealing triple tumors in prostate carcinoma, highlighting its diagnostic potential.
Galium-68 prostate-specific membrane antigen positron emission tomography combined with computed tomography (68Ga PSMA PET-CT) is receptor specific imaging, which has increasingly been used in the staging and restaging of prostate carcinoma (PCa). PSMA is type II transmembrane glycoprotein expressed in cytosol of normal prostatic tissue with 100-1000-fold over expression in PCa. It is also expressed in the endothelium of tumor-associated neo vasculature of non-prostatic solid tumor such as transitional cell and renal cell carcinoma, hepatocellular, thyroid, and brain cancers. We hereby present a case where PSMA PET scan showed three tumors proved on follow up imaging.
