Juvenile Nasopharyngeal Angiofibroma Symptoms & Causes

What are the symptoms of JNA?

In the early stages of the disease, patients with juvenile nasopharyngeal angiofibroma might not show any symptoms. As the tumor expands, however, the following symptoms may develop:

  • Difficulty breathing through the nose (due to airway obstruction)
  • Nosebleeds
  • Headaches
  • Double vision and other cranial nerve signs or symptoms if the tumor has expanded significantly

Patients rarely feel any significant pain.

What causes juvenile nasopharyngeal angiofibroma?

Scientists do not fully understand what causes JNA. Although it is not hereditary, children with family members who have familial adenomatous polyposis are slightly more likely to have JNA. Because the disease presents predominantly in adolescent boys, some studies have explored hormonal influences in JNA, but these studies have not been conclusive.
