This increases the pressure inside the skull. Fluid can build up in your head, a condition known as hydrocephalus. Large tumors may press on the brainstem, occasionally preventing the flow of cerebrospinal fluid between the brain and spinal cord. ComplicationsĪn acoustic neuroma may cause permanent complications, including: Each child of an affected parent has a 50-50 chance of inheriting it. This means that the gene related to the disorder can be passed to a child by just one parent. Neurofibromatosis type 2 is known as an autosomal dominant disorder. However, neurofibromatosis type 2 only accounts for about 5% of acoustic neuroma cases.Ī hallmark characteristic of neurofibromatosis type 2 is noncancerous tumors on the balance nerves on both sides of the head. The only confirmed risk factor for acoustic neuromas is having a parent with the rare genetic disorder neurofibromatosis type 2. The person has a 50% chance of having an unaffected child. A person with an autosomal dominant disorder - in this example, the father - has a 50% chance of having an affected child with one changed gene. You need only one changed gene to be affected by this type of disorder. It's located on one of the nonsex chromosomes, called autosomes. In an autosomal dominant disorder, the changed gene is a dominant gene.

See a health care professional if you notice hearing loss in one ear, ringing in your ear or balance problems.Įarly diagnosis of an acoustic neuroma may help keep the tumor from growing large enough to cause complications such as total hearing loss. Rarely, an acoustic neuroma may grow large enough to compress the brainstem and become life-threatening.

Facial numbness and, very rarely, weakness or loss of muscle movement.

Ringing in the affected ear, known as tinnitus.Hearing loss usually occurs on one side or is worse on one side.

In rare cases, hearing loss can be sudden.

Hearing loss, usually gradually over months to years.

Blood vessels or brain structures also can be affected by an acoustic neuroma.Īs the tumor grows, it may be more likely to cause more noticeable or worse symptoms.Ĭommon symptoms of an acoustic neuroma include:

The tumor also can put pressure on nearby nerves controlling facial muscles, known as the facial nerve, and sensation, known as the trigeminal nerve. Symptoms may occur because of the tumor's effects on the hearing and balance nerves. Symptoms of an acoustic neuroma are often easy to miss and may take years to develop.
