Abstract:
Herein, we present the results of 18F-FDG PET/CT and 68Ga-FAPI-4 PET/CT of a patient with metastatic Kaposi sarcoma. A 47-year-old man with suspected gastric cancer was referred to 18F-FDG PET/CT for diagnosis and staging. PET/CT detected increased 18F-FDG uptake in metastatic lymphadenopathies and liver lesions. 68Ga-FAPI-4 PET/CT was performed for ongoing clinical trial. Although 68Ga-FAPI-4 PET/CT may be a better alternative than 18F-FDG for the imaging of primary tumoral infiltrations in the stomach, 18F-FDG seems to be a more useful agent for the Kaposi sarcoma in determining the extent of the disease and the localization of metastatic lesions.
