Testing & Diagnosis for Pigmented villonodular synovitis (PVNS) in Children

Tests

How does a doctor know that it’s pigmented villonodular synovitis?
Diagnostic procedures for pigmented villonodular synovitis are used to determine the exact type of tumor your child has and whether the tumor has spread. These may include:

  • A physical exam, including neurologic function tests to measure your child’s reflexes, muscle strength, eye and mouth movement, coordination and alertness.
  • X-rays to produce images of internal tissues, bones, and organs onto film.
    • Magnetic resonance imaging (MRI) to produces detailed images of organs and structures within the body and/or spine
  • Arthography -- a special x-ray of the affected joint that involves the injection of a radiopaque substance directly into the affected area
