Testing & Diagnosis for Juvenile Nasopharyngeal Angiofibroma

How is JNA diagnosed?

There are several diagnostic procedures that may be used to determine whether your child has JNA. In addition to a complete medical history and physical examination, these may include:

  • Endoscopic evaluation – physicians will use an endoscopic (a flexible or rigid telescope like device, often attached to a camera, inserted into the nose) to determine the presence of the JNA and its degree of nasal airway obstruction.  This is typically performed in the Otolaryngology clinic.
  • Magnetic Resonance Imaging (MRI) – a diagnostic imaging exam involving a large magnet, radio waves, and a computer to produce 2- and 3-dimensional images of predominantly the body's soft tissue organs.
  • Computerized tomography scan (also called CT or CAT scan), this imaging technique uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically. CT scans provide greater detail of the body’s bony structures.
  • Pathology – Usually the combination of endoscopic evaluation, CT scan and MRI is sufficient to make the diagnosis of JNA. Rarely, your child’s doctors may also need to obtain a biopsy to confirm the diagnosis.

After the necessary tests are completed, our experts meet to review and discuss what they have learned about your child's condition. They then meet with you to discuss the results and outline the best treatment options for your child.
