What it is
Most occur for no known reason. Having neurofibromatosis type 2 makes them more likely, often in both ears.
Small tumours that are not growing are often watched with regular MRI scans. Others may be treated with focused radiotherapy (radiosurgery) or an operation.
Common signs
- Hearing loss in one ear, usually gradual
- Ringing or buzzing in one ear (tinnitus)
- Dizziness or problems with balance
- Less often, numbness or weakness on one side of the face
How it is usually diagnosed
- A hearing test (audiogram) showing loss mainly in one ear
- An MRI scan of the head, which confirms the diagnosis
Records worth keeping
Keeping these together makes each appointment easier, especially when you see a new doctor:
- Every audiogram, to compare hearing over time
- MRI reports, with the size of the tumour and the date
- Letters from ENT, neurosurgery or the radiosurgery team
- Treatment summaries and follow-up scan schedule
Questions to ask your doctor
- How large is it, and is it growing?
- How often will I have MRI scans?
- What are the options if it grows, and what are the risks to hearing and the face?
When to get help right away
Call 112 or go to the nearest emergency department if you have:
- A severe headache with vomiting, confusion or drowsiness
- Sudden loss of hearing in one ear (get seen within 24 hours)
- Sudden weakness of the face
