title: Infrasellar craniopharyngioma of the posterior nasal septum: a rare entity.
abstract: OBJECTIVE
  To report an unusual location of infrasellar craniopharyngioma in a peadiatric patient.
  
  
  METHODS
  A six-year-old boy presented with persistent bilateral nasal obstruction for one year. Clinical examination revealed a posterior choanal mass arising from septum and the finding was confirmed by paranasal sinuses computed tomography scan. He then underwent wide local excision. Histopathological examination confirmed the diagnosis of craniopharyngioma (adamantinomatous type). There were no signs and symptoms of recurrence after a year of followup.
  
  
  CONCLUSIONS
  Infracranial craniopharyngioma without sellar involvement is extremely rare. Persistent nasal obstruction without endocrine dysfunction is the common presentation. Radiological imaging is important to diagnose and assess the extent. The mainstay of treatment for infrasellar craniopharyngioma is surgery. Regular follow up is mandatory.
