Intracranial schwannomas most commonly arise from the vestibular portion of the Vestibulocochlear nerve (cranial nerve VIII). The central/proximal aspect of the nerve is myelinated by oligodendroglial cells whereas the distal/peripheral aspect is myelinated by Schwann cells. These distally located Schwann cells give rise to vestibular schwannomas that originate in the distal aspect of the nerve, usually within the internal auditory canal where it... Continue Reading →
