title: [Sphenoid sinus mucocele with recurrent visual disturbance].
abstract: We presented a case with sphenoid sinus mucocele associated with recurrent visual disturbance on the same side. A 22-year-old female showed two episodes of visual disturbance on the left eye for three months. She was diagnosed as acute retrobulbar optic neuritis and was treated with cortico-steroid. In two episodes visual disturbance improved in a week. MRI showed a mucocele in the left sphenoid sinus. No destruction of left optic canal was found in roentgenogram and the left optic nerve showed swelling with high intensity in T2-weighted MRI. Therefore the expansion of inflammation or edema in optic canal rather than direct compression by expanding mucocele was considered as pathogenesis of the visual disturbance. In a case of recurrent and unilateral visual disturbance, a mucocele of posterior paranasal sinus should be suspected in the differential diagnosis.
