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 eights 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.
