Facial Nerve Meningioma: A Case Mimicking Facial Nerve Schwannoma.

Facial nerve meningioma is exceedingly rare and tends to affect the geniculate ganglion. We present a case of facial nerve meningioma located in the internal auditory canal with a "labyrinthine tail," mimicking facial nerve schwannoma. The clinical and radiological features, growth patterns, and surgical management were reviewed. Progressive facial paralysis was the main syndrome, similar to other facial nerve tumors. When facial nerve function is worse than House-Brackmann grade III, surgical resection should be performed with facial nerve reconstruction.
