Abstract

We experienced rare case of temporal bone spontaneous leakage of cerebrospinal fluid (CSF) without prior history. <br>A 55-year-old male patient with hearing loss, headache and vertigo, was diagnosed of otitis media with effusion and received repeated myringotomy. The patient visited our hospital because of no improvement by previous treatments. <br>Computed tomography (CT) scan images of the temporal bone showed a bony defect in floor of the middle cranial fossa. In the same region, enhanced MRI showed a small soft tissue density which was thought as brain herniation. We performed surgical treatment with transmastoid approach. Sever CSF leakage was found in the region detected by CT scan image and MRI. And there was also identified a brain herniation without dura matter. <br>Brain herniation was coagulated by bipolar and the bone defect was repaired by autologous bone pate and temporal fascia. <br>One and half years after the operation, the CSF leakage was succseefully managed and there were no complaints and recurrence.
