Tumors throughout the nervous system
Neurofibromatosis causes tumors to form on nerves throughout the body. At UW Health, our Comprehensive Pediatric Neurocutaneous Disorders Clinic experts diagnose and treat neurofibromatosis and other disorders.
Types and causes
Types of neurofibromatosis
Neurofibromatosis causes tumors to develop on nerve tissue. These tumors are typically benign (non-cancerous).
Neurofibromatosis is a type of disorder that affects both the nervous system (neuro) and skin (cutaneous). These conditions are called neurocutaneous disorders.
There are three types of neurofibromatosis:
Tumors on specific nerves in the brain that affect hearing and balance
Tumors on or near the brain and spinal nerves
Other neurocutaneous disorders
Other neurocutaneous disorders include:
Von Hippel-Lindau disease
Genes cause these disorders, and they are present at birth (congenital). Genetic conditions can be passed down from parents or occur with no family history.
Symptoms and diagnosis
Signs and symptoms of each type of neurofibromatosis
Each type of neurofibromatosis has different signs and symptoms. These signs can develop throughout childhood. Most symptoms of neurofibromatosis are mild. Symptoms become more severe when tumors affect specific nerves or organs.
NF1 is the most common type of neurofibromatosis. Signs of NF1 usually appear after birth or during early childhood. NF1 symptoms include:
Bone deformities (curved spine or bowed leg)
Bumps in and under the skin (neurofibromas)
Freckling in the armpits or groin
Larger-than-average head size
Skin spots (often called café-au-lait spots)
Tiny bumps on the eye
NF2 is less common than NF1. Signs of NF2 usually appear in teens and young adults. NF2 symptoms include:
Ringing in the ears
Schwannomatosis is a rare form of neurofibromatosis. Signs of schwannomatosis typically develop after age 20. Symptoms include:
Numbness or weakness
Doctors typically diagnose this condition after symptoms develop. If your child is born with signs of neurofibromatosis, or it runs in your family, our doctors may suggest genetic testing.
When symptoms develop at later ages, our doctor may use several tests to make a diagnosis. These include:
X-rays or MRI tests
Treatments and research
Helping children live full lives
There is no cure for neurofibromatosis or other neurocutaneous disorders. Treatment can manage early complications and help your child live a full life.
At UW Health, we address the physical, emotional and social needs of children with tumors affecting their nervous system. Our treatments and therapies include:
Behavioral health care
Movement therapies (physical and occupational)
Surgery (for tumor removal or bone problems)
Our team is also committed to learning more about this condition and how best to treat it. We conduct clinical trials of new medications and therapies.
