BILATERAL ACOUSTIC NEUROFIBROMATOSIS

Bilateral acoustic neurofibromatosis is a nervous system genetic condition. Tumors develop on the nerve tissues. Neurofibromatosis problems primarily influence nerve cell tissue growth and development. Neurofibromatosis type 1 (NF1) and neurofibromatosis type 2 (NF2) are the two disorders. The most frequent kind of neurofibromatosis is NF1. Schwannomatosis, a third and more rare variety of neurofibromatosis, was recently discovered, but doctors still don’t know much about it.

TYPES

The two most common types of bilateral acoustic neurofibromatosis are:

  • Neurofibromatosis type 1
  • Neurofibromatosis type 2

SYMPTOMS

The symptoms of bilateral acoustic neurofibromatosis depends on its type. NF1 patients may experience the following symptoms:

  • Large head size
  • Short stature
  • Learning disabilities
  • Osteoporosis
  • High blood pressure
  • Several (usually six or more) café au lait spots
  • Nerve-related pain
  • Multiple freckles in the armpit or groin area
  • Bone deformities, including a twisted spine (scoliosis) or bowed legs
  • Tumors along the optic nerve
  • Tiny growths in the iris (colored area) of the eye

The following symptoms are common in people with Neurofibromatosis 2 (NF2):

  • Headaches
  • Poor balance
  • Dizziness
  • Loss of hearing
  • Uncoordinated walking
  • Weakness of the muscles of the face
  • Cataracts

DIAGNOSIS

Apart from a physical exam, assessment of medical history and symptoms, a variety of tests are used to diagnose neurofibromatosis, including:

  • Genetic testing
  • X-rays
  • Eye tests
  • Magnetic resonance imaging (MRI)
  • Biopsy of neurofibromas
  • Computerized tomography (CT) scans
  • Trials for particular symptoms, such as hearing or balance tests

TREATMENT

Neurofibromatosis has no known cure. The focus of treatment is on symptom management. There is no conventional treatment for NF, and many symptoms, such as café au lait spots, can be managed without medication. When therapy is required, may consider the following options:

  • Cataract removal surgery
  • Stereotactic radiosurgery
  • Surgery for bone problems, like scoliosis
  • Surgery to remove problem growths or tumors
  • Therapy (including physical therapy, counseling, or support groups)
  • Aggressive treatment of pain linked to the condition
  • Auditory brainstem and cochlear implants

Chemotherapy or radiation is needed if a tumor has turned malignant or cancerous. Consult your doctor about your condition’s treatment options. He or she may recommend the one that will help you manage your symptoms the most efficiently.
