Two years after resection of a left parietal glioma, a 46-year-old woman underwent 18F-FDG and 18F-DOPA brain PET/CT. 18FDG showed left parietal hypometabolism with crossed cerebellar diaschisis. No abnormally increased 18FDG activity was seen. 18F-DOPA PET/CT scan demonstrated focal left parietal uptake. Recurrent glioma was confirmed by surgical biopsy. 18F-DOPA may demonstrate abnormal amino acid metabolism in evaluation of recurrence of glioma.
