A Case of Isolated Abducens Nerve Palsy Caused by Primary Sphenoid Sinus Mucocele / 대한이비인후과학회지

ABSTRACT

Mucoceles of the sphenoid sinus are relatively rare and can lead to visual impairment, diplopia and external ophthalmoplegia. The ophthalmic symptoms seem to be caused mainly by compression or inflammatory changes. It is difficult to diagnose mucocele of the sphenoid sinus just on the basis of patient history or physical examination alone. CT scans and MRI help in the correct assessment of this lesion. We experienced one patient with a sphenoid sinus mucocele who presented simply with diplopia. The mucocele was managed successfully by endoscopic marsupialization.
