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).
Neurofibroma is a benign lesion of unknown origin that may occur in the peripheral nerve, soft tissue, skin or bone. It occurs as a solitary lesion more commonly than as a multiple lesion or in neurofibromatosis (NF-1 or von Recklinghausen's disease).he lesion visible on plain film may be a neurofibroma that has worked into the bone by pressure erosion or it may be a non-ossifying fibroma that is associated with NF-1.
