Abstract

In two patients with surgically proved CSF fistula through the facial nerve canal, MR and CT examinations showed smooth enlargement of the geniculate fossa with CSF signal. In the clinical setting of CSF otorrhea or rhinorrhea, the presence of an enlarged labyrinthine facial nerve canal and enlarged geniculate fossa on CT scans and CSF intensity on MR images strongly suggests a CSF fistula through the facial nerve canal.

摘要

在两名经手术证实存在通过面神经管的脑脊液瘘的患者中,磁共振成像(MR)和计算机断层扫描(CT)检查显示膝状窝有脑脊液信号的平滑扩大。在脑脊液耳漏或鼻漏的临床情况下,CT扫描显示迷路面神经管扩大和膝状窝扩大,以及MR图像上的脑脊液信号强度,强烈提示存在通过面神经管的脑脊液瘘。
