Abstract
- The orbital apex syndrome is a very rare complication of fungal sinusitis, as well as of other conditions, and is characterized by blindness, diplopia, proptosis of the eye and ophthalmoplegia. We present a case of diplopia caused by a fungal ball in the Onodi cell. A 62-year-old woman, diagnosed with orbital apex syndrome and suffering from ophthalmalgia and diplopia in the right eye, was presented to our outpatient clinic. Computed tomography showed a soft tissue lesion occupying the right Onodi cell with chronic inflammation. Patients who have an Onodi cell carry a high risk for optic nerve injury, so endoscopic sinus surgery using navigation was performed. Histopathology examination confirmed the diagnosis of a fungal ball. We experienced a rare case of a fungal ball in the Onodi cell, which caused damage to the adjacent cavernous sinus structure and led to diplopia and orbital pain. We present this case with a brief review of these disease entities.
