Mucoceles are benign, encapsulated, expansible, locally invasive masses within a paranasal sinus filled with mucus and lined by epithelium. Sphenoid sinus mucoceles are relatively rare, accounting for only 1% of all paranasal sinus mucoceles. Usually presenting with headache but can rarely result in visual defect, diplopia and at times, ptosis. We present two cases of sphenoid sinus mucocele where patient presented with ophthalmoplegia, ptosis and/or sudden onset vision loss. With the help of imaging studies like CT scan and MRI of paranasal sinus diagnosis was made and immediate surgical intervention was planned which resulted in acceptable improvement of symptoms and vision.
