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.
目的
描述一例由蝶筛隐窝黏液囊肿引起的压迫性视神经病变患者。
设计
介入性病例报告。
方法
一名73岁男性在白内障手术后10天出现左眼突发视力丧失。冠状位计算机断层扫描显示蝶筛隐窝有一均匀肿块。磁共振成像显示一个椭圆形病变压迫左侧视神经。
结果
鼻旁窦内镜微手术后，左眼视力改善。切除标本的组织病理学检查显示为黏液囊肿。
结论
眼科医生应意识到，蝶筛隐窝（鼻旁窦的一种解剖变异）中的黏液囊肿可能压迫视神经。
