Facial nerve schwannoma

Discussion:

Facial nerve schwannoma extending along the fallopian canal and bulkiest at the geniculate ganglion.

As schwannomas elsewhere, facial nerve schwannoma originates from the surface of the nerve, and displace and splay the nerve fibers over their eccentric growth. It can occur in any segment of the facial nerve and have a tendency to involve multiple segments. There is a known predilection for the region of the geniculate ganglion.
