Which of the following diseases or disorders is most likely associated with neurofibromatosis type 2?
Neurofibromatosis type 2 (NF2) is a hereditary condition most commonly associated with bilateral vestibular schwannomas, also known as acoustic neuromas. These are benign (noncancerous) tumors that occur on the nerves for balance and hearing leading to the inner ear.

- Magnetic resonance imaging (MRI) scan of the brain and spinal cord to determine the location of the tumors.
- Hearing tests.
- Vision tests.
- Genetic testing.
Can a person have both NF1 and NF2?

When is NF2 usually diagnosed?
Symptoms of NF2 are typically detected between the ages of 18 and 24 years, while NF1 is diagnosed in infancy or early childhood. In NF2, benign tumors called schwannomas grow on nerves throughout the nervous system and often cause impaired hearing and vision.
How do you test for NF2?
Prenatal diagnosis of NF2 can be done with 65-percent accuracy through: chorionic villus sampling (CVS): CVS is used in situations where there is a known family history of a certain genetic disorder.In this procedure, a sample of chorionic villus cells is taken from the placenta.
What is a type 2 neurofibromatosis diagnosis?
Diagnosis of Neurofibromatosis (NF) Type 2. The diagnostic criteria for NF2 has been established by a consensus of experts. A person is thought to have NF2 if they have a: Confirmed (definite) diagnosis of NF2: bilateral vestibular schwannomas (may also be known as acoustic neuroma)
What is the age of onset of Neurofibromatosis 2 (NF2)?
Summary. Neurofibromatosis 2 (NF2) is characterized by bilateral vestibular schwannomas with associated symptoms of tinnitus, hearing loss, and balance dysfunction. The average age of onset is 18 to 24 years. Almost all affected individuals develop bilateral vestibular schwannomas by age 30 years.
How often should I be screened for neurofibromatosis type 2?
Individuals with neurofibromatosis type 2 should be screened regularly for these issues through: Annual brain MRIs starting at age 10 years and continuing until at least 40 years of age. Baseline spine MRIs to screen for tumors should be performed at time of diagnosis and repeated if symptoms develop.
How many people in the world have neurofibromatosis type 2?
