Facial Paralysis from Facial Nerve Tumors

A facial paralysis that begins insidiously and progresses in severity is characteristic of a tumor arising from the facial nerve or, more commonly, a tumor that arises from adjacent structures and secondarily invades the facial nerve.

Diagnosis for Facial Paralysis from Facial Nerve Tumors

If facial paralysis is suspected to be due to a tumor arising from the facial nerve, MRI imaging is used for detection.
