Abstract

A 64-year-old woman with persistent headaches and vision disturbances underwent 18 F-(2S,4R)-4-fluoroglutamine ( 18 F-FGln) PET/CT due to MRI contraindications. Imaging revealed a sellar mass with high radiotracer uptake (SUVmax 7.17), later confirmed as a WHO grade I meningioma. This case highlights the potential of 18 F-FGln PET/CT in detecting meningiomas, leveraging their glutamine metabolism. Given the tumor's metabolic profile, glutaminase inhibitors may offer novel therapeutic avenues. Further research is warranted to explore the mechanistic basis of 18 F-FGln uptake in meningiomas and its implications for diagnosis and treatment.
