title: Sphenoid sinus mucocele presenting with unilateral visual loss: a case report.
abstract: OBJECTIVE
  Mucoceles of the sphenoid sinus are rare and may remain undiagnosed until symptoms arise due to the compression of surrounding structures. Because of its close proximity to the sphenoid sinus, the optic nerve may be compressed and visual impairment may result.
  
  
  METHODS
  We report on a case of sphenoid sinus mucocele presenting with unilateral visual loss as the only symptom in a 72-year-old patient. Physical examination, computerised tomography, magnetic resonance imaging, bacteriological cultures and histopathological evaluation were used to make the diagnosis. The patient underwent endoscopic sinus surgery for drainage and marsupialisation of the mucocele. Intravenous ceftriaxone was administered over the following three days, and the patient was discharged on the third post-operative day. In the post-operative period, a slight improvement in vision was observed.
  
  
  CONCLUSIONS
  Early diagnosis and prompt surgical intervention are imperative in patients with sphenoid sinus mucoceles presenting with acute visual loss.
