Schwannoma tumor
A schwannoma tumor is a tumor made of Schwann cells; Schwann cells make up the myelin sheath (or covering) of nerve cells.
Schwannomatosis is one form of a genetic disorder called neurofibromatosis (NF) that has only recently been recognized.

A vestibular schwannoma (also known as acoustic neuroma, acoustic neurinoma, or acoustic neurilemoma) is a benign, usually slow-growing tumor that develops from the balance and hearing nerves supplying the inner ear.
Alternate Names : Vestibular schwannoma, Tumor - acoustic, Cerebellopontine angle tumor, Angle tumor
Definition ...
This problem sometimes is called an acoustic or vestibular schwannoma. If an acoustic neuroma is not diagnosed or treated, it can grow through the skull bones that make up the middle ear and press on important structures in the brain.
Schwannoma
A schwannoma is a tumour of the nerve sheath (fatty covering of the nerves). It can occur in the major nerves of the head or the peripheral nerves (outside the brain and spinal cord).

schwannomatosis
The primary feature which distinguishes schwannomatosis from NF1 and NF2 is the growth of multiple schwannomas throughout the body except the vestibular nerve is not involved.
Schwannoma (shwah-NO-ma): A type of benign brain tumor that begins in the Schwann cells, which produce the myelin that protects the acoustic nerve � the nerve of hearing.
Screening: Checking for disease when there are no symptoms.
schwannoma A tumor of the peripheral nervous system that arises in the nerve sheath (protective covering). It is almost always benign, but rare malignant schwannomas have been reported.
Schwannomas
Schwannomas are benign tumors, similar to meningiomas. They arise from the supporting cells of the nerves leaving the brain, and are most common on the nerves that control hearing and balance.

Scientists have classified the disorders as neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2), and schwannomatosis, a type that was once considered to be a variation of NF2. NF1 is the more common type of the neurofibromatoses.

The tumour that develops on the nerves is called a schwannoma. In the majority of cases, the schwannomas develop on both sides of the body (bilaterally) but not necessarily at the same time.
GISTs are mesenchymal in origin and are immunohistochemically distinct from leiomyosarcomas, schwannomas, and fibrosarcomas with which they are often classified. They can be distinguished by being CD34 positive and CD117 positive.
Acoustic neuroma, commonly refered to as vestibular schwannoma, is an intracranial tumor that forms in the vestibulocochlear nerve.
The most frequent early symptoms of vestibular schwannomas are hearing loss, ringing in the ears (tinnitus), and problems with balance. In most cases, these tumors occur in both ears by age 30.

Also known as vestibular schwannoma, acoustic neuroma is an uncommon cause of hearing loss.
Hearing deficit is most commonly associated with NF2 as a result of tumor (schwannoma) growth on the auditory nerves.
An acoustic neuroma, also called a vestibular schwannoma, is a benign primary intracranial tumor of the myelin-forming cells of the vestibulocochlear nerve (CN VIII).

Plexiform neuromas and schwannomas are neural tumors occurring along the course of a nerve. The Lisch nodules characteristic of the disease are evident in the iris on slit lamp examination, usually by the teens.
It should be noted that vestibular function testing can be abnormal in about 25% of patients with MV. Other potential diagnoses (e.g., vestibular schwannoma) should be ruled out by the appropriate imaging studies such as MRI.
