Neurofibromatosis type 2 is a disorder characterized by the growth of noncancerous tumors in the nervous system. The most common tumors associated with neurofibromatosis type 2 are called vestibular schwannomas or acoustic neuromas. These growths develop along the nerve that carries information from the inner ear to the brain (the auditory nerve).
Neurofibromatosis is a genetic disorder that can cause tumors in various parts of the central nervous system (CNS). There are two types of neurofibromatosis. Type 1, the more common kind, usually occurs outside of the CNS. Type 2 occurs within the CNS. Type 2 neurofibromatosis causes multiple CNS tumors, including neurofibromas, multiple meningiomas, bilateral vestibular schwannomas, optic nerve gliomas, and spinal cord tumors.
