BACKGROUND
The evolution of sphenoid sinus meningoencephaloceles and cerebrospinal fluid (CSF) rhinorrhea is poorly understood.
CASE DESCRIPTION
We present a case demonstrating the gradual evolution of encephaloceles from both the lateral walls of a previously normal sphenoid sinus in a patient with dural arteriovenous fistula; the CSF leak that developed after staged embolization of the dural arteriovenous fistula was managed by an endoscopic endonasal transpterygoid approach.
CONCLUSIONS
We suggest that over a period of time, chronic elevation of intracranial pressure can result in gradual erosion of the lateral wall of the sphenoid with development of meningoencephaloceles and CSF leaks.
背景
蝶窦脑膜脑膨出和脑脊液鼻漏的演变过程尚不清楚。
病例描述
我们报告一例病例，该病例显示了硬脑膜动静脉瘘患者蝶窦双侧侧壁原本正常的脑膜脑膨出的逐渐演变过程；硬脑膜动静脉瘘分期栓塞后出现的脑脊液漏通过鼻内镜经翼突入路进行处理。
结论
我们认为，在一段时间内，颅内压的慢性升高可导致蝶窦侧壁逐渐侵蚀，进而发展为脑膜脑膨出和脑脊液漏。
