    Abstract:
    Mixed neuroendocrine carcinoma-acinar carcinoma is an uncommon histological type of neuroendocrine prostate cancer. It has been rarely reported in de novo prostate malignancies. In this case, we present 68 Ga-PSMA (prostate-specific membrane antigen), 68 Ga-FAPI, and 18 F-FDG PET/CT findings in the de novo form of mixed large-cell neuroendocrine carcinoma-acinar adenocarcinoma of the prostate. Different levels of radiotracer uptake were observed in different metastatic sites on 68 Ga-PSMA, 68 Ga-FAPI, and 18 F-FDG PET/CT. This case demonstrates that the multitracer PET/CT strategy may be used for the noninvasive detection of the intermetastatic heterogeneity in metastatic neuroendocrine prostate cancer.
