vestibular schwannoma is the most common tumor of the cerebellopontine angle in adults. It is approximately 8-9% of all intracranial tumors. The term “vestibular schwannoma” is preferred over<unk>  which is a misnomer.<unk>  is a noncancerous tumor.  In 1777, Eduard Sandifort first described<unk> . In 1822, Wishart described Bilateral<unk>  for the first time. It grows slowly from an overproduction of Schwann cells and is additionally called a vestibular schwannoma. The tumor then presses on the hearing and balance nerves within the internal ear. Schwann cells normally encircle and support nerve fibers. An outsized tumor can compress the facial nerve, which controls facial muscles and sensation or it can compress brain structures.<unk>  may be classified according to the findings on magnetic resonance imaging (MRI), microscopic histopathology, association with neurofibromatosis type 2 or not. On microscopic histopathological analysis, an<unk>  may display two types of growth patterns: Antoni type A and Antoni type B. Screening for<unk>  is not recommended at any age. Approximately 50% of all<unk> s grow slowly 1 - 2 mm in one year. The growth rate is more rapid (greater than 2 mm/year) in about 20% of the patients. The tumor does not metastasize to other parts of the body. Widespread access to sensitive neuro-diagnostic imaging has led to a remarkable rise in the detection of vestibular schwannomas.  Gadolinium-enhanced MRI scan is the definitive diagnostic test for<unk>  and can identify tumors as small as 1-2 millimeters in diameter.<unk>  characterized by hypointense lesion on T1-weighted MRI, and hyperintense lesion on T2-weighted MRI of brain. Treatment strategies are often divided into an observational wait-and-scan approach, irradiation, microsurgery, and a mixture of these methods. Each strategy features a set of benefits and limitations. Complication include long-term facial-nerve paralysis, bilateral hearing loss, or chronic dizziness or imbalance and these may require rehabilitative intervention.
