Neurofibromatosis 2 (NF2) is a genetic disorder in which tumors form on the nerves of the brain and spine (the central nervous system).
Although it has a similar name to neurofibromatosis type 1, it is a different and separate condition.
NF2; Bilateral acoustic neurofibromatosis; Central bilateral acoustic NF
NF2 is passed down through families in an autosomal dominant pattern. This means that if one parent has NF2, any child of that parent has a 50% chance of inheriting the condition.
The main risk factor is having a family history of the condition.
Symptoms of NF2 include:
- Balance problems
- Cataracts at a young age
- Changes in vision
- Coffee-colored marks on the skin (café-au-lait)
- Hearing loss
- Ringing and noises in the ears
- Weakness of the face
Exams and Tests
- Brain and spinal tumors
- Hearing-related (acoustic) tumors
- Skin tumors
- Genetic testing
- Medical history
- Physical examination
Acoustic neuromas can be observed, or treated with surgery or radiation.
Patients may benefit from genetic counseling.
Every year, patients with NF2 should be evaluated with:
- MRI of the brain and spinal cord
- Hearing and speech evaluation
- Eye exam
