A Case of Optic Neuropathy Caused by Sphenoid Sinus Mucocele / 대한이비인후과학회지

ABSTRACT

Sphenoid sinus mucoceles represent 1% of all paranasal sinus mucoceles. Patients with a sphenoid sinus mucocele often experience only ophthalmic symptoms such as visual impairment, diplopia and external ophthalmoplegia. The ophthalmic symptoms seem to be caused mainly by compression or inflammatory changes. CT scan and MRI help in the correct assessment of this lesion. We have experienced a rare case of optic neuropathy caused by sphenoid sinus mucocele which is likely to misdiagnose to optic neuritis. The mucocele was managed successfully by endoscopic marsupialization. We report this case with a review of related literature.
