Epiglottic Polymorphous Adenocarcinoma With Multiple Bone Metastases Detected by 68Ga-FAPI PET/CT

Polymorphous adenocarcinoma (PAC) is generally an indolent tumor that mostly commonly affects the minor salivary gland. Polymorphous adenocarcinoma with distant metastases is extremely rare. In this case, we reported 18F-FDG and 68Ga-FAPI PET/CT imaging findings in a rare case of epiglottic PAC with multiple bone metastases. 68Ga-FAPI PET/CT showed superiority over 18F-FDG PET/CT for detecting the primary and metastatic PAC. This case highlighted that 68Ga-FAPI may be a promising radiopharmaceutical in the diagnosis of PAC, especially for detecting the PACs arising in uncommon sites.
