Testing & Diagnosis for Schwannoma (Neurilemoma) in Children

In addition to undergoing a complete physical exam and medical history, your child may have one or more of the following tests:

  • X-ray - a diagnostic test that uses invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs onto film. Neurofibromas are not seen well on x-rays, but they should be obtained to ensure that the adjacent bone is not involved.
  • Ultrasound - an imaging technology that uses high frequency sound waves to view internal organs and structures and produce diagnostic pictures of the human body. Ultrasound is sometimes useful to detect soft tissue masses.
  • Magnetic Resonance Imaging (MRI) - a diagnostic procedure that uses a combination of large magnets, radiofrequencies and a computer to produce detailed images of organs and structures within the body.
  • Biopsy of the tumor - A simple surgical procedure during which a tissue sample from the tumor is taken and then viewed under a microscope.
