Introduction

Facial nerve schwannomas are benign, encapsulated tumors that arise from the facial nerve sheath [1, 2, 3]. Schwannomas of the facial nerve can arise from either the extratemporal or intratemporal course of this nerve [4]. Facial nerve schwannomas most commonly arise from intracranial and intratemporal part of the facial nerve. Facial nerve schwannoma arising from the extratemporal course of facial nerve accounts for only 9% of all facial nerve schwannomas [5]. Intraparotid facial nerve schwannoma is an even rarer entity and accounts for 0.5–1.5% of all parotid tumors [6]. Literature search has have described less than 100 cases of intraparotid facial nerve schwannomas.

Intraparotid facial nerve schwannoma is a diagnostic challenge due to its rarity and non-specific radiological features. It may often be confused with other benign tumors of parotid as was the case in one of our patients. Facial nerve schwannoma must be considered as a possibility in a slow-growing parotid...
