Acoustic schwannoma

An acoustic schwannoma (also known as acoustic neuroma or vestibular neuroma) is a benign tumor that develops around a nerve in the inner ear.

This tumor grows around and compresses either the auditory (cochlear -for hearing) or vestibular (for balance) nerves leading from your ear to the brain.

The TrueScan scan is not intended to look at individual nerves of the central nervous system, thus this finding (if present) represents a large mass lesion.
