Abstract

Facial nerve schwannomas are uncommon tumors. A 40-year-old female presented with left-side facial weakness. Computed tomography[CT] imaging showed a $3\;{\times}\;2cm$ lesion on the posterior portion of the left middle cranial fossa. The mass abutted the anterior aspect of the left petrous bone with a wide erosive change involving the area of the left facial nerve ganglion [geniculate ganglion]. A well-circumscribed extra-axial mass was seen on magnetic resonance imaging[MRI]. The tumor was completely removed through subtemporal approach and the patient was discharged without additional neurological deficit. This rare case is discussed and a review of the relevant literature is presented.
