The only known risk factor for acoustic neuroma is having a parent with the rare genetic disorder neurofibromatosis type 2, but this accounts for only a small number of cases. A hallmark characteristic of neurofibromatosis type 2 is the development of benign tumors on the balance nerves on both sides of your head, as well as on other nerves.

Neurofibromatosis type 2 (NF2) is known as an autosomal dominant disorder, meaning that the mutation can be passed on by just one parent (dominant gene). Each child of an affected parent has a 50-50 chance of inheriting it.

Another possible risk factor that may be associated with acoustic neuroma includes childhood exposure to low-dose radiation of the head and neck.
