title: Optic neuropathy secondary to a sphenoid-ethmoidal mucocele: Case report.
abstract: METHODS
  The case is presented of a 51-year old male patient with a history of blunt trauma in the frontal region and a one-year history of vision loss, proptosis and paresis of the lateral rectus muscle of the right eye. A right ethmoid and bilateral sphenoid mucocele was diagnosed. Drainage was performed using an external and endoscopic approach with improvement in symptoms without recurrence at 10 months.
  
  
  CONCLUSIONS
  Sphenoid mucoceles represent 1% of all mucoceles and may present with different clinical manifestations. Surgical excision is the treatment of choice, and early intervention is indicated to prevent complications.
