The onodi cell is a posterior ethmoidal cell that is pneumatized laterally or superiorly to the sphenoid sinus with close proximity to the optic nerve. A mucocele, a benign, expansile, cyst-like lesion of the paranasal sinuses, may uncommonly involve the onodi cell causing compression of the optic nerve and nearby structures. In this paper, we report a rare case of onodi cell mucocele causing orbital apex syndrome, with prompt recovery after endoscopic removal. However, optic neuropathy did not improve and the patient remained blind.

“…Of these patients, the time interval between presentation and surgery ranged from a few days [2] to three weeks [9]. Presenting visual acuities ranged from 20/50 [3] to hand movements [6], and postoperative acuity improvement ranged from 20/30 [7] to 20/20 [4, 6–8]. Six patients received corticosteroid therapy either prior to or following the surgical decompression.…”

“…Six patients received corticosteroid therapy either prior to or following the surgical decompression. Three patients had previous sinonasal conditions [3, 7, 10], which may have increased the possibility of blockage of the ostium and formation of the mucocele. Our patient had no previous nasal pathology.…”

Purpose. To report on a patient with compressive optic neuropathy secondary to an Onodi cell mucocele, who fully recovered visual function following surgery. Method. Case report. Results. A 28-year-old male was admitted with a right visual acuity of 20/100 following treatment for an initial diagnosis of optic neuritis. Subsequent examination suggested compressive optic neuropathy, and neuroimaging confirmed the presence of an Onodi mucocele compressing the optic nerve. The patient underwent a right endonasal sphenoethmoidectomy with decompression 5 weeks after the initial onset of symptoms. Three weeks following surgery, the visual acuity was 20/20, and there was complete resolution of the visual field defect, which has remained stable at 1 year. Conclusion. Onodi cell mucocele should be included in the differential diagnosis of a young patient with compressive optic neuropathy. Surgical decompression should be considered even when symptoms have been present for over a month.

“…A literature review showed few reports of Onodi cell mucoceles 7–10 and polyps 11 that result in optic neuropathies. Indeed, only one case of orbital apex syndrome secondary to Onodi cell mucocele has been reported to date.…”

Background:To report an unusual case of compressive optic neuropathy secondary to a large onodi air cell.Method:Case report.Results:A 50 year-old gentlemen presented to the eye clinic with left eye painless loss of vision for one day. Visual acuity was counting finger in the left eye with a positive relative afferent pupillary defect (RAPD). Dilated left fundus examination revealed a pale optic disc. A computed tomography of orbit and brain showed a large left sphenoid sinus with onodi-cell-like projection on the left superior margin of left optic canal impinging on the left optic nerve. He was referred to the otorhinolaryngology team and subsequently underwent left optic nerve decompression. Post-operatively, his left visual acuity improved to 6/60 with reversal of RAPD.Conclusion:There are many causes of optic neuropathy and compressive optic neuropathy due to large onodi air cell is uncommon. Acute unilateral loss of vision heralds from a multitude of sinister causes and junior residents should be vigilant that onodi air cell pneumotisation could be one of them.
