Isolated Liver Metastasis Detected by Ga-68-PSMA PET/CT in Newly Diagnosed Prostate Cancer

Lymph nodes, bones, and liver are the most typical metastatic sites for prostate cancer. However, isolated liver metastasis from prostate cancer is extremely rare. Here, we report a 75-year-old man with newly diagnosed prostate adenocarcinoma, with isolated liver metastasis detected by Ga-68-PSMA (Ga-68-prostate-specific membrane antigen) PET/CT. There was no sign of regional or distant metastases elsewhere. This case highlights the value of Ga-68-PSMA PET/CT in detecting a very uncommon solitary liver metastasis from prostate cancer.
