A case of infected sphenoid mucocele in which the patient complained of chronic sore throat and in which routine intranasal endoscopy contributed significantly to the diagnosis is presented. The pathology of mucocele and endoscopic sinus surgery as the treatment for sphenoid sinus mucocele is discussed.
