외반신경마비를 동반한 접형동 농성점액종 1례

The sphenoid sinus mucocele, which was first described by John Berg in 1889, is relatively uncommon but it is the most common space-occupying lesion of the sphenoid sinus. The sphenoid sinus pyocele with intracranial extension and/or cranial nerve impairment is much rarer. As the mucocele enlarges, there is pressure resorption of the surrounding bone, exposure and stretch of the dura with pain and impairment of contigious cranial nerves. There is difficulty in diagnosis of the sphenoid sinus due to different presentation of symptoms and signs and it should be differentiated from other intracranial tumors. A careful treatment is needed because of its anatomic position.

We describe a case of sphenoid sinus pyocele with right abducens nerve paralysis cured by endoscopic sinus surgery.
