Her abdominal CT revealed an retroperitoneal mass in the left upper quadrant of the abdomen. F-18-FDG PET/CT performed for metabolic characterization showed low to moderate heterogenous FDG uptake. Ga-68-fibroblast activation protein-specific inhibitor (FAPI)-04 PET/CT performed according to a research carried out in our department showed high heterogenous radiopharmaceutical uptake. The patient was diagnosed with leiomyosarcoma after R0 tumor resection. This case showed that Ga-68-FAPI-04 PET/CT could be a promising radiopharmaceutical in the evaluation of leiomyosarcomas.eninfo:eu-repo/semantics/closedAccessLeiomyosarcomaFapiFdgPet/CtEditorial4612E594E597WOS:0007144149000143473541310.1097/RLU.0000000000003673Q1
