Diagnosis

To diagnosis a peripheral nerve tumor, your doctor may ask you about signs and symptoms, discuss your medical history, and perform both a general physical and neurological exam. He or she may order several tests to help pinpoint the cause of your signs and symptoms.

• Magnetic resonance imaging (MRI). This scan uses a magnet and radio waves to produce a detailed, 3-D view of your nerves and surrounding tissue.
• Computerized tomography (CT). A CT scanner rotates around your body to record a series of images. A computer uses the images to make a detailed view of your peripheral nerve tumor so that your doctor can evaluate how it may be affecting you.
• Electromyogram (EMG). For this test, your doctor places small needles in your muscles so an electromyography instrument can record the electrical activity in your muscle as you try to move it.
• Nerve conduction study. You're likely to have this test along with your EMG. It measures how quickly your nerves carry electrical signals to your muscles.
• Tumor biopsy. If imaging tests identify a nerve tumor, your doctor may remove and analyze a small sample of cells (biopsy) from your tumor. Depending on the tumor's size and location, you may need local or general anesthesia during the biopsy. Sometimes this is the only way to determine whether a tumor is cancerous.
• Nerve biopsy. If you have a condition such as progressive peripheral neuropathy or enlarged nerves that mimic nerve tumors, your doctor may take a nerve biopsy.

Peripheral nerve tumors are uncommon. Ask your doctor if he or she is experienced in diagnosing and treating them. If needed, seek a second opinion.

Coping and support

Dealing with the possibility of permanent complications of peripheral nerve tumors and deciding which treatment would be best for you can be quite stressful. Here are some suggestions you may find helpful:

• Educate yourself about peripheral nerve tumors. The more you know, the better prepared you'll be to make good choices about treatment. Besides talking to your doctor, you may want to talk to a counselor or a social worker. Or you may find it helpful to talk to other people who've had a condition like yours and learn more about their experiences during and after treatment.

• Maintain a strong support system. Family and friends can help you as you go through this difficult time. Sometimes, though, you may find the concern and understanding of other people with a condition like yours especially comforting.

  Your doctor or a social worker may be able to put you in touch with a support group.
