Benign peripheral nerve tumor care at Mayo Clinic

Your Mayo Clinic care team

At Mayo Clinic, doctors trained in diagnosing and treating conditions of the nervous system (neurologists and neurosurgeons) work with doctors trained in hereditary conditions (geneticists) and specialists trained in rehabilitation) to evaluate and treat people who have benign peripheral nerve tumors.

Advanced diagnosis and treatment

People with benign peripheral nerve tumors have access to the latest in diagnosis and treatment technology. A range of diagnostic tests are available at Mayo Clinic, including:

  • 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.
  • Nerve biopsy. If you have a condition such as a progressive peripheral neuropathy or enlarged nerves that mimic nerve tumors, your doctor may take a nerve biopsy.

A comprehensive treatment plan

If your peripheral nerve tumor is benign, your Mayo Clinic doctor will recommend either observation or surgery.

Your doctor may recommend observation if your tumor is in a place that makes removal difficult or if the tumor is small and causes no problems. Observation includes regular checkups and imaging tests to see if your tumor is growing.

More commonly, your doctor will recommend surgery to remove the tumor. At Mayo Clinic, highly trained neurosurgeons use the latest in surgical techniques to remove the tumor while sparing nearby tissue and minimizing damage to nerves. Your doctor may then use a brace or splint to keep your arm or leg in a position that helps you to heal.

After surgery, you may need physical rehabilitation. Mayo Clinic physical therapists and occupational therapists can guide you through specific exercises that keep your muscles and joints active, prevent stiffness, and help to restore your function and feeling.

Pediatric expertise

Occasionally, children and adolescents get some type of nerve tumor. At Mayo Clinic, your child's treatment team can include doctors trained in treating conditions of the brain, muscles and nerves, including pediatric neurologists and neurosurgeons, doctors trained in hereditary conditions (geneticists), and specialists trained in rehabilitation.

Expertise and rankings


Mayo Clinic doctors are respected for their experience diagnosing and treating nerve disorders, such as benign peripheral nerve tumors. Each year, more than 2,000 people with benign peripheral nerve tumors seek care at Mayo Clinic.


Mayo Clinic researchers in the Department of Neurology study the causes, progression, genetics and treatment options for benign peripheral nerve tumors. Experts in Mayo Clinic's Department of Clinical Genomics provide access to the latest testing techniques, when medically appropriate, to evaluate benign peripheral nerve tumors caused by hereditary conditions. Mayo researchers also conduct clinical trials.
