The Onodi cell, which is a posterior ethmoid cell that gets pneumatized far laterally and to some degree superiorly to the sphenoid sinus, is intimately associated with the optic nerve. The problem with most cases of Onodi cells is that acute visual loss may occur in association with a compression to the optic nerve by a mucocele of an Onodi cell. We report, with a review of literature, a case of fungal infection in Onodi cells with acute visual loss in a 71 year-old female patient, who was treated by endoscopic sinus surgery with electrical drill and steroid therapy.
