What is a spinal schwannoma?

A schwannoma is a spinal tumor that arises from the lining of the nerve cells of the spine. The nerves of the spine are insulated by a protective sheath called myelin, which transmits nerve impulses throughout the body. Schwann cells create the myelin sheath of the nerves.
