Causes, incidence, and risk factors Return to top These tumors are thought to arise when there is a defect in a certain tumor suppressor gene, which normally prevents tumors from occurring. The cause of the genetic defect is not known. However, acoustic neuroma is often linked with the genetic disorder neurofibromatosis type 2 Acoustic neuromas are relatively uncommon, but they are one of the most common types of brain tumors. They affect approximately 1 out of 100,000 people per year. The tumor is most commonly located at the base of the brain, where the auditory nerve leaves the skull cavity and enters the bony structure of the inner ear.

One scenario might be: you can't hear anything when you put the telephone to one of your ears. Your doctor now delivers the bad news that you have a brain tumor, AND the Good News that it is perfectly benign. You are bombarded by different therapy options (Gamma Knife, Surgery, etc.) including the idea to forget about the whole thing. Everyone and their brother and/or sister has a strong opinion; only you are left to make the decision. Welcome to the world of acoustic neuromas! This tumor (called a "schwannoma") arises from the myelin forming cells (Schwann cells") of the 8th cranial nerve at the point where the peripheral part of the nerve meets the brain part of the nerve (called "Hensen's node"). Hensen's node is usually located in the inner ear canal that leads to our hearing apparatus, called the "acoustic meatus." This nerve is actually three nerves in one, two "vestibular" nerves (upon which the tumor actually grows) and the hearing nerve. Immediately associated with these nerves is the 7th cranial nerve, the nerve that controls the muscles of the face, salivation, tearing, and taste. The tumor grows just next to the brain stem, and when enlarged may actually compress it. Larger tumors also may involve the swallowing nerves down below, as well as the 5th nerve above which controls sensation to the face and eye. In other words, this is a very tightly packed and difficult area for involvement. Patients may present any combination of symptoms related to malfunction of these nerves, depending on the size, the pressure and location of the tumor.

References Brain tumours Cells within the brain normally grow in an orderly and controlled way, but if for some reason this order is disrupted, the cells continue to divide and form a lump or tumour. The tumour may be benign , where the cells do not spread from the original site, or malignant (cancerous), where the cells invade and destroy surrounding tissue and may spread to other parts of the brain. Tumours affecting the whole central nervous system (CNS), which is made up of the brain, spinal cord and a network of nerves throughout the body, are fairly rare. Just over 5000 new tumours are diagnosed each year in the UK. Many of these are malignant. back to top Acoustic neuromas Most brain tumours are named after the type of cells from which they develop.

My Acoustic Neuroma Experience This is the story of my diagnosis and treatment of acoustic neuroma.  I decided to provide a detailed diary of my experience and decisions as an aid to others with this condition.  Perhaps I got a little carried away with the detail, but I wanted to be sure I didn't leave anything out. I'm an engineer, not a doctor, and any statements or opinons on this website regarding treatment are only my opinion as an AN patient, nothing more.  My quotes of some the various people I spoke with about my condition are limited by the accuracy of my memory. My stated opinions of each of these people is based on my limited personal experience with them, and my opinion might improve or decline if I knew them better. 2002 UPDATE!

ACOUSTIC NEUROMA-THE BASIC FACTS Diagnosis Home Origin/Cause Microscopy Symptoms ... Postoperative Small tumors A small tumor is also called intracanalicular because it is confined within the bony internal auditory canal (figure). A patient with such a tumor may have hearing loss, ringing in the ear or ear noise, and vertigo or dizziness. Medium tumors A medium sized acoustic neuroma is one which has extended from the bony canal into the brain cavity, but has not yet produced pressure on the brain itself (figure). Patients with such tumors have worsening of their hearing, difficulty in balance, in addition to dizziness, and occasionally, the onset of headaches due to irritation of the lining of the brain called dura. Some patients may experience numbness of the mid-face or diminished sensation in the eye during the later stages. Large tumors A large tumor is one which is extended out of the internal auditory canal in to the brain cavity and is sufficiently large to produce pressure on the brain and disturb vital centers in the brain (figure). During this stage, all previous symptoms worsen; facial twitch and weakness may occur, and finally patient may develop hydrocephalus due to the blockage of the cavity which contains CSF-the resultant symptoms are headache, visual loss and double vision.

37. ACOUSTIC NEUROMA The several names used for this benign tumor include acoustic neuroma, Much acoustic neuroma data was presented at a National Institute of Health http://www.medhelp.org/lib/neuronom.htm

ACOUSTIC NEUROMA Acoustic neuromas are being more frequently diagnosed as those with hearing loss and sometimes other symptoms are obtaining MRIs (Magnetic Resonance Imaging scans) which can show small tumors at an early stage. The several names used for this benign tumor include acoustic neuroma, acoustic neuronoma and vestibular schwannoma. It involves the 8th cranial nerve which has two branches - acoustic and vestibular and under the microscope resembles schwann cells. For that reason, vestibular schwannoma is a synonym. The phrase "benign" generally implies a course unmarked by progression or death. Unfortunately, in the brain, this is not necessarily the situation. Because the brain is so delicate and encased in bone, there is little extra space for unusual growths of any type. The incidence of acoustic neuromas is modest - approximately 1 per 100,000 people per year. It's equivalent to approximately 2,500 people being diagnosed each year in the United States. That is of little relief to those diagnosed. Because MRI can detect lesions which were previously not visible by other means, it is likely that the true incidence is higher. Symptoms include decreased hearing, ringing in the ears and a change in balance. While acoustic neuromas can affect either ear and sometimes both ears, most often it is unilateral.

38. UPDATE IN ACOUSTIC NEUROMAS acoustic neuroma treatment is undergoing a marked revolution. acoustic neuromas are benign tumors that affect the eighth cranial nerve a nerve that comes http://www.medhelp.org/lib/acneuro2.htm

UPDATE IN ACOUSTIC NEUROMAS by: Gil Lederman, M.D. Acoustic neuroma treatment is undergoing a marked revolution. Acoustic neuromas are benign tumors that affect the eighth cranial nerve - a nerve that comes from the brain and is delicately located adjacent to important other structures such as the facial nerve and brain stem. It is a tumor that affects 2,000 to 3,000 Americans annually. Those with acoustic neuromas most frequently have diminished hearing. It is often first noticed because of the decreased ability to use a telephone on the involved side. Ringing in the ear, imbalance and later, pain, numbness or weakness of the face can occur. In the past, treatment remained in the domain of surgeons. Unfortunately, surgery is associated with marked morbidity and occasional mortality. A recent paper from the University of Pittsburgh revealed a complication rate such that more than one-half the patients lost facial function after surgery and a significant number of patients required re-operation for complications from the open surgery. The surgical data was compared to single fraction radiosurgery and a marked diminishment in complications was found using radiation. Now, enhancement of radiosurgery technique has been developed at Staten Island University Hospital. This data was presented at The 77th Annual American Radium Society meeting in Paris. The data shows excellent control of acoustic neuromas with no complications.
