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 leading to the inner ear. Although these tumors are benign, they can cause hearing and balance problems. * Schwannomas of other nerves * Meningiomas * Gliomas (including Ependymoma of the brain or spinal cord)
