Purpose |
To describe a patient with compressive optic neuropathy caused by a mucocele in an Onodi cell.
Design |
Interventional case report.
Methods |
A 73-year-old man complained of sudden visual loss in the left eye 10 days after cataract surgery. Coronal computed tomography showed a homogeneous mass in an Onodi cell. Magnetic resonance imaging revealed an oval-shaped lesion that compressed the left optic nerve.
Results |
After endoscopic microsurgery of the paranasal sinus, visual acuity in the left eye improved. Histopathological examination of the excised specimen showed a mucocele.
Conclusions |
Ophthalmologists should be aware that the mucocele in the Onodi cell, an anatomical variation of the paranasal sinus, may compress the optic nerve.
