A case of inner ear anomalies associated with recurrent meningitis found in a 66-year-old female is reported. The patient had had 2 episodes of meningitis in the previous one year period. Multidetector-row CT of the temporal bone and three-demensional fast imaging employing steady-state acquisition MRI revealed dysplasia of the bony labyrinth and enlarged fundus of the internal auditory canal (IAC). During surgical treatment, we confirmed the cerebrospinal fluid (CSF) leakage through a bony defect in the stapedial footplate. The inner ear was obliterated and contained small pieces of temporal fascia. A meningitis or CSF leakage due to inner ear malformation is extreamly rear condition for neurosurgeon. Though we always have to take it into condideration as a cause of CSF leakage.
报告了一例66岁女性中发现的与复发性脑膜炎相关的内耳异常病例。该患者在过去一年中有2次脑膜炎发作。颞骨多排探测器CT和采用稳态采集的三维快速成像MRI显示骨迷路发育异常和内耳道（IAC）底扩大。在手术治疗期间，我们通过镫骨足板的骨缺损确认了脑脊液（CSF）漏。内耳被闭塞，包含小块颞筋膜。内耳畸形导致的脑膜炎或脑脊液漏对于神经外科医生来说是极其罕见的情况。尽管我们始终必须将其作为脑脊液漏的一个原因加以考虑。
