A neuroma is a generally benign
tumor that grows on the peripheral nerves
. It was previously referred to as a schwannoma due to the most commonly affected cells being Schwann cells located around nerves. Neuromas can affect
different nerves, such as spinal column nerves and particularly those of the cervical region, yet the acoustic nerve in the inner ear, involved in both hearing and some balance control, is also frequently affected, leading to the term vestibular schwannoma as the acoustic nerve is also known as the 8th cranial nerve or the vestibulocochlear nerve. A neuroma can cause a wide variety of symptoms, primarily painful, at the innervated area, and surgical removal is sometimes necessary.
