Increased Ga-68-Fapi-04 Uptake In Schmorl Node In A Patient With Gastric Cancer

A 78-year-old man with a newly diagnosed gastric adenocarcinoma underwent F-18-FDG and Ga-68-FAPI-04 PET/CT before treatment. Both F-18-FDG and Ga-68-FAPI-04 PET/CT demonstrated intense radioactivity in the gastric cancer. However, the benign Schmorl node in the inferior endplate of the T5 vertebrae showed increased uptake of Ga-68-FAPI-04, which was not FDG avid. Two months after radical gastrectomy of the gastric cancer (pT1aN0M0, IA), a follow-up CT showed that the Schmorl node in T5 vertebrae remained unchanged.
