Neurofibromatosis 2 (NF2) is a disorder in which tumors form on the nerves of the brain and spine (the central nervous system). It is passed down (inherited) in families.
Although it has a similar name to neurofibromatosis type 1, it is a different and separate condition.
NF2; Bilateral acoustic neurofibromatosis; Bilateral vestibular schwannomas; Central neurofibromatosis
NF2 can be 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.
Acoustic tumors can be observed, or treated with surgery or radiation.
People with this disorder may benefit from genetic counseling.
People with NF2 should be regularly evaluated with these tests:
- MRI of the brain and spinal cord
- Hearing and speech evaluation
- Eye exam
