Intense 68Ga-DOTA-FAPI-04 Uptake in Diffuse Sclerotic Skeletal Metastases of Gastric Cancer.

ABSTRACT

ABSTRACT Diffuse sclerotic metastases of the bone as initial presentation at gastric carcinoma are very rare. We present a 48-year-old man who was examined for pancytopenia and diagnosed with gastric cancer. 18F-FDG PET/CT showed moderate uptake in the primary gastric tumor and mild uptake in diffuse sclerotic metastatic lesions in the bone matrix, whereas 68Ga-DOTA-FAPI-04 showed mild uptake in the gastric lesion and intense uptake at the whole skeleton.
