FOLH1 and metastatic prostate carcinoma: We report an index case in Ecuador in which combined gallium-68 prostate-specific membrane antigen (<sup>68</sup>Ga-PSMA) and fluorine-18 fluorodeoxyglucose (<sup>18</sup>F-FDG) positron emission tomography/computed tomography (PET/CT) was used for the comprehensive characterization and longitudinal follow-up of a patient with high-volume metastatic prostate cancer, highlighting the complementary metabolic and molecular information provided by both imaging tracers.
