OBJECTIVE
We report a unique case of anatomical variation of the extracranial course of the optic nerve running in the floor of the sphenoid sinus.
METHOD
Clinical and radiological findings are presented.
RESULTS
A 39-year-old woman with Turner syndrome presented with severe headache associated with visual disturbances. Magnetic resonance imaging revealed a mass presumed to be a sella meningioma. Computed tomography of the paranasal sinuses was undertaken to help plan surgical removal via an endoscopic trans-sphenoidal approach; this scan revealed an atypical extracranial course of the optic nerve, running in the floor of the sphenoid sinus.
目的
我们报告一例独特的病例，其视神经颅外段走行于蝶窦底部，存在解剖变异。
方法
介绍临床和影像学检查结果。
结果
一名患有特纳综合征的39岁女性，出现与视觉障碍相关的严重头痛。磁共振成像显示一个肿块，推测为鞍区脑膜瘤。进行了鼻窦计算机断层扫描，以帮助规划通过内镜经蝶窦入路进行手术切除；该扫描显示视神经颅外段走行异常，位于蝶窦底部。
