RESUMO
A 58-year-old woman with breast carcinoma, after mastectomy, radiotherapy, and chemotherapy, underwent a whole-body F-18 FDG PET/CT for restaging, which revealed multiple skeletal metastasis. Hypometabolism was noted in the right frontal lobe. The patient subsequently underwent a C-11 methionine brain scan, which demonstrated multiple dural-based metastatic foci confirmed on contrast-enhanced MR. FDG PET has limitations in brain tumor detection. Amino acid tracers are particularly attractive for imaging of brain tumors because of relatively high tumor to brain activity ratios.
