Acoustic neuroma
Acoustic neuromas (more correctly called vestibular schwannomas) account for approximately five percent of intracranial tumours and 90 percent of cerebellopontine angle
Features can be predicted by the affected cranial nerves
Bilateral acoustic neuromas are seen in neurofibromatosis type 2
MRI of the cerebellopontine angle is the investigation of choice
Features can be predicted by the affected cranial nerves
- cranial nerve VIII: hearing loss, vertigo, tinnitus
- cranial nerve V: absent corneal reflex
- cranial nerve VII: facial palsy
