[Facial nerve schwannomas. Report of a case].

Facial nerve schwannomas are relatively uncommon lesions. The clinical features depend upon the localization and extent of the lesion. The most common presenting symptom is that of a slowly progressive facial nerve palsy, because of facial schwannoma usually are located near the geniculate ganglion. A case of facial schwannoma is reported: a woman presenting a sudden facial palsy did not respond to medical and rehabilitation treatment. First, a Bell's palsy was diagnosed and then the facial nerve schwannoma with imaging techniques. A review about facial nerve schwannomas is reported.
