title: [Bilateral sphenoid sinus mucocele presenting as abducens nerve palsy: case report].
abstract: Mucocele is a rare, benign, cystic tumor affecting primarily adults. It arises within the sphenoid sinus and invades the orbit through bony destruction. The most frequent locations are frontal and fronto-ethmoidal; sphenoidal forms are rarer, and bilaterality is exceptionally rare. Ophthalmological signs with the risk of blindness required emergency treatment. The authors report a case of bilateral sphenoid mucocele presenting as an isolated abducens nerve palsy, the etiological investigation confirmed the diagnosis of sphenoid mucocele, and the treatment consisted of a surgical marsupialization through an endonasal endoscopic approach.
