title: Evaluation of metastatic meningioma with 2-deoxy-2-[18F]fluoro-D-glucose PET/CT.
abstract: OBJECTIVE
  The purpose of this study was to characterize the 2-deoxy-2-[18F]fluoro-D-glucose (FDG) PET/CT imaging findings of sacral metastatic meningioma.
  
  
  METHODS
  An 18-year-old woman with a history of metastatic meningioma, who presented with intractable pain and spasm of the right lower extremity, underwent FDG PET/CT imaging.
  
  
  RESULTS
  FDG PET/CT scan demonstrated a moderately hypermetabolic sacral mass. The biopsy of the lesion was consistent with a high-grade malignant meningioma.
  
  
  CONCLUSIONS
  Although meningioma is typically a benign tumor, in rare instances, it metastasizes. The current case example exhibits moderately increased metabolism despite findings of high-grade malignancy on biopsy.
