title: Recurrent meningitis and persistence of craniopharyngeal canal: case report.
abstract: OBJECTIVE
  Craniopharyngeal Canal is a rare malformation of the sphenoid bone described in up to 0.42% of the asymptomatic population. It's been related to the development of the Rathke's pouch during embrionary period although some authors think it's a vestige of a former vascular channel.
  
  
  METHODS
  This report details a case of a four and a half years old child that developed recurrent meningitis associated with this anomaly. Its origin, clinical manifestations and treatment options are discussed.
  
  
  CONCLUSIONS
  Due to its low incidence and diagnostic difficulties, a high suspicion index is required while studying a case of recurrent meningitis or CSF leakage. Surgical approach is still controversial.
