  Acoustic neuroma - WrongDiagnosis.com
Acoustic neuroma: A benign tumor of the 8th cranial nerve which lies in the tube connecting the inner ear to the brain.
Acoustic neuroma is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH).
This means that Acoustic neuroma, or a subtype of Acoustic neuroma, affects less than 200,000 people in the US population.

Acoustic neuroma (or Vestibular Schwannoma) is a benign tumor of the acoustic nerve (more properly the vestibulocochlear nerve) just after it has left the brainstem, in the pontine angle.
Two risks of radiation treatment are carcinogenic progression of the acoustic neuroma (conversion from benign to malignant) or induction of other tumors (such as glioblastoma) in the nearby irradiated brain tissue.
Due to the possibility of regrowth and the possibility of tumorienic progression or secondary tumors, it is essential that radiation treatments for acoustic neuromas be followed by yearly MRI for the rest of the patient's life.

 Acoustic Neuroma
An acoustic neuroma (sometimes called a neurinoma or vestibular schwannoma) is a benign (non-cancerous) tissue growth that arises on the eighth cranial nerve.
The acoustic portion of the eighth nerve goes to the cochlea of the ear and transmits hearing while the vestibular portion goes to the semicircular canals which are responsible for detecting motion (acceleration more technically) and hence are involved in the sense of balance.
Acoustic neuromas are occasionally discovered incidentally, in the course of evaluating another problem, or when the tumor is very small and there are few symptoms.

Acoustic neuromas (AN) are benign, generally slow growing tumors that intimately involve the seventh and eighth cranial nerve (CN VII and VIII) in a portion of the brain commonly referred to as the cerebellar-pontine angle (CPA).
However, in nearly all patients with acoustic neuromas, a hearing test (or audiogram), should be done to measure the damage inflicted by the tumor on the cochlear nerve.
For nearly every patient with a very large acoustic neuroma (defined as greater than 4-5 cm in diameter) that is severely pressing on and compromising brain function, it is widely believed (although not universally so) that open microsurgical resection is the treatment of choice.

 Acoustic Neuroma / Stereotactic Radiosurgery
In a benign tumor such as acoustic neuroma, with a very slow cell turnover, it will take some time for the radiation to affect the cells in a way that can be detected clinically or by imaging.
Acoustic neuromas sometimes increase in size temporarily as a reaction to the Gamma Knife treatment.
Even though most acoustic neuromas arise from the balance nerve (and not from the adjacent hearing nerve), hearing loss in the affected ear is a much more frequent presenting symptom than balance disturbance.

 Acoustic Neuroma Brain Tumors
An acoustic neuroma is a benign (noncancerous) brain tumor that starts in the cells that wrap around the auditory (hearing) nerve in the head.
Acoustic neuromas are a form of schwannoma, a tumor that originates in the cells that form a protective sheath around the body's nerve fibers.
When the acoustic neuroma is found early, doctors may order a magnetic resonance imaging (MRI) scan and hearing tests, which may include a special technique to test nerve impulses as they travel to the brain.

 Acoustic neuroma
An acoustic neuroma is a benign (non-cancerous) growth that arises from the sheath surrounding the eighth cranial nerve.
The term ‘acoustic neuroma’ is, strictly speaking, incorrect because the tumour arises usually on the part of the eighth nerve which deals with balance rather than sound.
Acoustic neuroma is diagnosed only once per year per 100,000 people so from that point of view it is uncommon.

The goals of stereotactic radiosurgery in the treatment of acoustic neuromas as well as metastases, meningiomas, arteriovenous malformations and brain tumors are obviously to stop tumor growth, avoid invasive surgery and eliminate the need for any surgical intervention as best as possible.

However, for patients with large acoustic tumors (over 3 cm in extracanalicular diameter) and those with progressive neurologic deficits that require brainstem decompression, surgical resection (total or subtotal) is the preferred option.
We believe that all patients with newly diagnosed, residual, or recurrent acoustic tumors (less than 3 cm in extracanalicular diameter) are now suitable radiosurgery candidates (11,15).
