title: Calcifying Pseudoneoplasm of the Neuraxis Arising From the Sacral Canal: Case Report and Review of the Literature.
abstract: BACKGROUND
  Calcifying pseudoneoplasm of the spine is an extremely rare lesion and has not yet been reported in the sacral canal.
  
  
  METHODS
  We present the first known case of a calcifying pseudoneoplasm of the neuraxis arising from the sacral canal and discuss the clinicopathological features and neuroradiological findings of this lesion.
  
  
  CONCLUSIONS
  Calcifying pseudoneoplasm of the neuraxis can occur throughout the spine, including the sacral canal, and should be included in the differential diagnosis of intraspinal calcified lesions.
