Schwannomas

Schwannomas, according to the National Cancer Institute, are mostly benign tumors of the peripheral nervous system that arise in the nerve sheath (protective covering). Rare malignant schwannomas have been reported, but benign schwannomas represent the overwhelming majority.

The most common schwannoma is the acoustic neuroma. This is a tumor of the eighth cranial nerve. These tumors can also occur on other cranial nerves such as the fifth cranial nerve (trigeminal nerve).

Symptoms

The symptoms relate to the size and location of the tumor. Acoustic neuromas usually cause hearing loss. Fifth nerve tumors can cause pain in the face.

Diagnosis

As always, the first steps in diagnosis are a careful history and physical examination. MRI scanning without and with intravenous contrast enhancement is the usual next step.

Treatment

The treatment of schwannomas depends upon a number of factors including size, location and medical condition of the patient. Surgery is a frequent treatment for these tumors. Sometimes, stereotactic radiosurgery might be used to treat certain tumors.
