Acoustic Neuroma

Acoustic neuromas are slow-growing tumors that typically originate in the cerebellopontine angle, a small space between the brain and the inner ear.

Early symptoms of an acoustic neuroma may be mild and include:

Gradual hearing loss on one side

Tinnitus (ringing or buzzing in the ear)

Vertigo (feeling of dizziness or spinning)

Unbalance

As the tumor grows, it can compress the eighth cranial nerve and other nearby nerves, causing more severe symptoms, such as:

Facial numbness or weakness

Difficulty swallowing

Headache

Double vision

In rare cases, a large acoustic neuroma can cause life-threatening complications, such as hydrocephalus (a buildup of fluid in the brain).

The exact cause of acoustic neuroma is unknown, but they are thought to be associated with a gene mutation that causes Schwann cells to grow uncontrollably. Schwann cells are cells that wrap around and support nerve fibers.

Acoustic neuromas are diagnosed using a combination of physical exams, imaging tests, and hearing tests. MRI is the modality of choice. an enhancing mass at a CP angle with an intracanalicular component that expands the porus acousticous and internal auditory canal.

Differencial Diagnosis would include meningioma or epidermoid.

Treatment options for acoustic neuroma include:

Monitoring: Small acoustic neuromas that are not causing symptoms may be monitored with regular imaging tests and hearing tests to watch for growth or changes.

Radiation therapy: Radiation therapy can be used to shrink the tumor and reduce symptoms.

Surgery: Surgery is the most common treatment for acoustic neuroma. The goal of surgery is to remove the tumor completely, while preserving as much hearing and facial function as possible.

The prognosis for acoustic neuroma is generally good. Most people who are treated for acoustic neuroma do well and have a normal life expectancy. However, some people may experience permanent hearing loss, facial numbness or weakness, or balance problems.

If you are experiencing any of the symptoms of acoustic neuroma, it is important to see a doctor right away. Early diagnosis and treatment can help to improve your outcome.
