Abstract

Invasive fungal sinusitis is common in immunodeficiency patients and can spread into the orbit or intracranial cavity. The Onodi cell, which is one of the anatomical variations of the ethmoid sinus, refers to the space that has been pneumatized superolateral to the sphenoid sinus. We experienced a case of invasive fungal sinusitis that caused vision loss by invading the Onodi cells. Endoscopic sinus surgery and antifungal treatment successfully recovered the patient’s vision and we herein report on the case with a review of the literature.
