title: Craniospinal dissemination of filum myxopapillary ependymoma following spinal trauma: case report and literature review.
abstract: BACKGROUND
  Myxopapillary ependymoma is a rare benign variant of ependymoma, occurring most commonly in the cauda equina/filum terminale of the spinal cord. It is rare in pediatric patients. Dissemination of the myxopapillary ependymoma along the neuraxis is uncommon both in adults and pediatric patients.
  
  
  METHODS
  We report a 16-year-old boy with dissemination of the myxopapillary ependymoma along the neuraxis following spinal trauma. The possible mechanisms of tumor dissemination are discussed with a review of the literature.
