Abstract
- The authors present a case of malignant papillary meningioma of the petrous bone involving the whole petrous bone which extended to the left cerebellopontine angle and internal jugular vein extracranially. A 46-year-old male patient was presented with a 3-years history of the left otalgia and subsequent deafness with left facial nerve palsy. Neurological examination revealed a complete palsy of the left eighth nerve, and incomplete palsies of the left 7th, 9th, 11th, and 12th cranial nerves. Magnetic resonance imaging and computerized tomographic scan demonstrate a huge mass in cerebellopontine angle which involved the whole petrous bone, suboccipital bone and internal jugular vein. The tumor was totally resected using the transjugular approach with modified petrous bone resection. Neuropathologic examination revealed a papillary meningioma.
