Hi musa333,
I'm certain you mean "Acoustic neuroma", a benign tumor associated with the ear.
Mayo Clinic:
What is an acoustic tumor?
"An acoustic neuroma is a noncancerous (benign) tumor of the acoustic
nerve, which carries sound from the inner ear to the brain. The exact
cause usually isn't known. But acoustic neuromas are often associated
with neurofibromatosis 2, an inherited disorder characterized by
tumors of the cranial and spinal nerves. Acoustic neuromas are one of
the most common types of brain tumors.
Acoustic tumors grow very slowly. As they grow, they push against the
brain but they don't spread into the brain. Signs and symptoms may
include:
* Hearing loss in one ear
* Ringing (tinnitus) in the affected ear
* Dizziness
* Loss of balance
A doctor may confirm a diagnosis by:
* Magnetic resonance imaging (MRI) of the head
* Computerized tomography (CT) scan of the head
Treatment may include:
* Surgical removal of the tumor
* Gamma knife radiosurgery to slow or stop the growth of the tumor"

What is an acoustic neuroma?
"An acoustic neuroma (sometimes also termed a neurinoma or vestibular
schwannoma) is a benign or non-cancerous growth that arises from the
8th or vestibulo-cochlear nerve."
http://www.med.umn.edu/otol/library/aneuroma/origin.htm
Symptoms:
* Hearing loss
* Ringing in the ears (tinnitus)
* Dizziness (vertigo)
* Difficulty in balance (imbalance or dysequilibrium)
* Fullness or pressure in the ears
* Facial numbness or paralysis (for very large tumors)
http://www.med.umn.edu/otol/library/aneuroma/symptom.htm
Diagnosis:
"A majority of the patients can be diagnosed by imaging techniques
(MRI/CT scans) which is the gold standard."
http://www.med.umn.edu/otol/library/aneuroma/diagnos.htm
There are 3 treatment options available for AN
*Observation
*Microsurgical removal (partial or total)
*Stereotactic radiation therapy (radiosurgery)

RADIOLOGICAL EXAMINATIONS:
Computed Tomography (CT) - Head:
"Computed tomography (CT), sometimes called CAT scan, uses special
x-ray equipment to obtain many images from different angles, and then
join them together to show a cross-section of body tissues and organs.
CT scanning provides more detailed information on head injuries, brain
tumors, and other brain diseases than do regular radiographs (plain
x-ray films). It also can show bone, soft tissues, and blood vessels
in the same images. CT of the head and brain is a patient-friendly
exam that involves radiation exposure."

MR Imaging (MRI) - Head:
"Magnetic resonance imaging (MRI) uses radio waves and a strong
magnetic field rather than x-rays to provide remarkably clear and
detailed pictures of internal organs and tissues. This technique has
proved very helpful to radiologists in diagnosing tumors of the brain
as well as disorders of the eyes and the inner ear. It requires
specialized equipment and expertise and allows evaluation of some body
structures that may not be as visible with other imaging methods."

I hope this helps. If you have any questions, please post a
clarification request before closing/rating my answer.
Thank you,
