For the initial staging, the patient underwent F-18-fluorodeoxyglucose (FDG) positron emission tomography/computerized tomography (PET/CT) imaging, which demonstrated mild F-18-FDG uptake in the multiple expansile osteolytic bone lesions, but no remarkable atypical F-18-FDG uptake in the liver lesion on low-doses CT. An additional PET/CT scan was performed to evaluate the prostate-specific membrane antigen (PSMA) expression, which has recently been reported to be a potential biological marker in a variety of tumors including HCC. High PSMA uptake was recorded in both the metastatic bone lesions and the primary liver lesion/tumor by the Ga-68-PSMA PET/CT.enginfo:eu-repo/semantics/openAccessHepatocellular carcinomabone metastasesPET/CTGa-68-PSMAF-18-FDGarticle293135138000579707200008
