Summary Summary. Schwannomatosis is a rare form of neurofibromatosis that is primarily characterized by multiple schwannomas (benign tumors of the nervous system) in the absence of bilateral (affecting both sides) vestibular schwannomas.
Some of the most common are described below: 1  Meningiomas grow from the meninges. 2  Schwannomas are benign tumors that arise from Schwann cells, which produce the myelin that protects peripheral nerves. 3  Craniopharyngiomas develop in the region of the pituitary gland near the hypothalamus.
