Abstract

18F-PSMA is a promising tracer for both staging and detection of biochemical recurrence in prostate cancer. PSMA is also expressed in the endothelium of tumor-associated neovasculature of various solid malignancies possibly due to tumor-associated angiogenic factors and endothelial cell sprouting. We report a case of a 59-year-old man with known case of prostate cancer underwent 18F-PSMA for restaging. 18F-PSMA PET/CT shows multiple lytic bone lesions with high PSMA expression. Histopathological evaluation showed metastatic angiosarcoma. 18F-PSMA expression in the angiosarcoma can be potentially guided to radionuclide legend therapy.
