title: Juvenile intradural chordoma: case report.
abstract: OBJECTIVE
  We report the youngest known case of a prepontine intradural chordoma. These tumors are exceedingly rare. Unlike their more common extradural counterparts, no recurrence of an intradural chordoma has been reported.
  
  
  METHODS
  A 9-year-old boy underwent diagnostic imaging for evaluation of headaches. Although neurologically intact, a magnetic resonance imaging scan revealed a large prepontine mass with focal enhancement.
  
  
  METHODS
  Endoscopic-assisted gross total resection was attained with staged bilateral retrosigmoid approaches. There were no additional adjuvant therapies. At the time of the 1-year follow-up evaluation, the patient had no recurrence.
  
  
  CONCLUSIONS
  By using an endoscopic-assisted procedure, we achieved complete resection of an intradural chordoma offering a potential for surgical cure. Resection is particularly advantageous because it spares the young child the need for radiation treatment. Close follow-up is warranted because we postulate that this tumor exists in a biological continuum between benign notochordal hamartomatous remnants and typical invasive chordomas.
