Abstract

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

摘要

一名 46 岁女性在切除左顶叶胶质瘤两年后，进行了 F-FDG 和 F-DOPA 脑 PET/CT 检查。FDG 显示左顶叶代谢减低伴交叉性小脑失联络。未见异常增高的 FDG 活性。F-DOPA PET/CT 扫描显示左顶叶局灶性摄取。手术活检证实为复发性胶质瘤。F-DOPA 可能在评估胶质瘤复发时显示异常氨基酸代谢。
