Tests and procedures used to diagnose malignant peripheral nerve sheath tumors include:

  • Neurological examination. A detailed, comprehensive neurological examination helps your doctor understand your symptoms and gather clues about your diagnosis.
  • Imaging tests. Imaging tests help doctors understand the size of a tumor and look for signs that cancer has spread to other areas of the body. Imaging tests may include MRI, magnetic resonance neurography, CT and positron emission tomography (PET).
  • Removing a sample of tissue for testing (biopsy). A biopsy may be obtained by a radiologist before surgery or by a surgeon during surgery. Using sophisticated laboratory processes, a doctor who specializes in analyzing blood and body tissue (pathologist) analyzes the tumor cells. The information gathered in the lab may help your doctor better understand your prognosis and your treatment options.
