Schwannoma is a noncancerous (benign) tumor also known as vestibular schwannoma or neurilemmoma. Schwannomas involve the Schwann cells in the protective covering of nerves, called the myelin sheath, and can develop anywhere Schwann cells are present. As schwannomas grow, they can cause pressure, irritation or damage to the nerve itself.
