Understanding the Types of Neurofibromatosis and Schwannomatosis
There are three kinds of neurofibromatosis. Each affects different parts of your body:
- Neurofibromatosis type 1 (NF1): The most common type, this is usually found in early childhood and can affect you for your whole life. It often causes harmless tumors under your skin called (neurofibromas) and brown areas, or café-au-lait spots, on your skin. It can also affect your vision and other parts of your body.
- NF2-related schwannomatosis: If you have NF2, you were most likely diagnosed in adolescence or early adulthood. Previously known as neurofibromatosis type 2, it affects nerves linked to hearing and balance (auditory and vestibular nerves). Benign nerve tumors (acoustic neuromas or vestibular schwannomas) are common in this rarer type of neurofibromatosis.
- Schwannomatosis: The rarest type of neurofibromatosis, this causes lumps (schwannomas) to grow on your nerves. These lumps are usually benign, but they can still hurt and make it harder to move or keep your balance. Pain may occur even when tumors aren’t easy to see or feel. Providers identify the types of schwannomatosis from the gene changes that cause them.
Diagnosing Neurofibromatosis and Schwannomatosis at Cleveland Clinic
Neurofibromatosis and schwannomatosis show up differently for each person. That’s why it’s important to get a diagnosis and treatment from experienced healthcare providers. When you visit Cleveland Clinic, you’ll have an expert team to help you understand what to expect from tests and treatment.
What to expect at your first visit
When you come for your first appointment, your provider will take time to get to know you and understand your condition. They’ll ask a lot of questions so they can get a better idea of what’s happening, like:
- If you already know you have neurofibromatosis, when were you diagnosed?
- Have you had ongoing pain, numbness or weakness that hasn’t had a clear explanation?
- What symptoms do you have and when did you first notice them?
- Have these symptoms been getting worse and affecting your daily life?
- Have you been diagnosed with any other health conditions?
- Does anyone else in your biological family have neurofibromatosis?
Your provider will also do a physical exam to check for signs of neurofibromatosis, like tumors, skin spots or heart problems. You might also have a hearing test and an eye exam.
If you have tumors you can see or feel, your provider will take a small sample (biopsy) to check if it’s cancerous. You may also have blood tests to check your overall health and rule out other issues.
Our team may also order imaging tests, like an MRI or CT scan, to get a closer look at your brain and nervous system.
Because these are genetic conditions — neurofibromatosis and schwannomatosis are passed down through families — your provider will also likely suggest genetic testing as part of your care.

Treating Neurofibromatosis and Schwannomatosis at Cleveland Clinic
Neurofibromatosis and schwannomatosis are long-term conditions that require ongoing care. Treatment focuses on managing symptoms, monitoring tumors and addressing complications that affect your daily life. Symptoms and concerns we commonly help manage include:
Treatment can look different for each person, so your care team will help create a plan that’s right for you. This might include medicine, surgery or regular check-ups to keep an eye on things.
Regular check-ups and tests
You’ll have regular testing and visits with your care team. These visits are a great time to share an update on your symptoms and any other concerns. We’ll use these check-ups to track tumor growth, vision and hearing problems, and more. These visits also allow us to treat any complications quickly.
Sometimes, your provider may choose to keep an eye on your symptoms rather than start treatment right away. This may be the case if symptoms are stable and aren’t interfering with your daily life.
Your providers can recommend oral or IV (intravenous, through a vein) medications to help manage pain, or physical therapy to help with movement problems. They may also talk with you about hearing aids, glasses and other tools to help with everyday living.
If you have schwannomatosis, these visits are also an important time to talk about pain — what’s helping, what’s not, and whether treatment adjustments could improve comfort and function.
Surgery
Tumors from neurofibromatosis can cause problems with hearing, balance, movement and more. Your care team may suggest surgery to remove all or part of a tumor, depending on its size, where it is and your symptoms. Some types of neurofibromatosis can also lead to cataracts, cloudy areas on your eyes’ lenses that can cause vision loss. We may recommend surgery for those, too.
Radiation therapy and chemotherapy
We can also shrink tumors using radiation or chemotherapy. Computer-guided Gamma Knife® surgery treats tumors with highly focused radiation in a single dose.
Support and counseling
Living with a long-term condition like neurofibromatosis or schwannomatosis can be physically and emotionally challenging — and you may decide you need extra help. Our caring providers can connect you and your family with counselors, support groups and other resources.

Taking care of yourself when you have neurofibromatosis or schwannomatosis means making good choices every day.
