Facial nerve schwannomas: A case series with an analysis of imaging findings.

Facial nerve schwannomas (FNSs) are rare benign tumors arising from the Schwann cells of the sheath of the facial nerve. These tumors may arise anywhere along the course of the facial nerve. Owing to their rarity and nonspecific clinical and radiological presentations, the preoperative diagnosis of FNSs is exceedingly difficult.
