What is Schwannoma?

Schwannom, also called Neobilemmoma, is a benign, slow -growing mass or a tumor resulting from Schwann cells. Schwann's cells are components of myelin chicks that cover axons or branches of nerve cells. They are involved in the proper functioning of the nerve cells, their development and regeneration and the leadership of nerve pulses throughout the body. The cause of schwannoma is still unknown, although certain factors such as genetic predisposition may increase the risk of tumor development. For example, individuals who have a family history of neurofibomatosis or von Reklinghausen's disease have a higher risk of developing this condition.

The cranial nerves in the brain are often affected by schwannom. 12 cranial nerves are the most commonly affected vestibular nerves, which are found in the ears for hearing; trigeminal nerve involved in the feeling of face and motor functions such as chewing and swallowing ;; And the glossopharyngeal nerve that gives the taste of the tongue. When Schwannoma developsIn one of the cranial nerves, usually the loss of function follows, although sometimes the tumor may occur without symptoms and is observed by the way only during scanning of computer tomography (CT) or magnetic resonance (MRI) made for other medical reasons.

patients with cranial nerve schwannomas, often depending on the nerve involved. As the tumor increases, the nerve and other adjacent structures in the brain may compress. In vestibular schwannoma or acoustic neuroma, the patient may experience ringing in the ears, insensitivity of the face, gradual loss of hearing and loss of balance. Glossopharyngeal Schwannoma can manifest itself with hoarseness and swallow difficulties. Trigeminal schwannomas may occur with face pain and double vision.

In addition to cranial nerves, Schwannoma can also develop in the nerves of the legs, arms and lower back. The pain sometimes feels when the tumor gradually grows. When he touches afterThe affected area can also be felt, described as an electric shock.

biopsy is usually needed to diagnose the tumor and to exclude malignant schwannoma. The treatment involves removing the tumor surgically by separation from the nerve, ideally without damaging the nerve function. Radiotherapy and chemotherapy are also integrated to reduce the tumor or prevent its further growth. However, the tumors may repeat in the same place after surgical removal if they are not completely removed.
