Definition of Juvenile angiofibroma:

Juvenile angiofibroma is a noncancerous growth of the back of the nose or upper throat.

Causes, incidence, and risk factors:

Juvenile angiofibroma is not very common. It is usually found in adolescent boys. The tumor contains many blood vessels, spreads within the area in which it started (locally invasive), and can cause bone damage.

Symptoms:

• Difficulty breathing through the nose
• Easy bruising
• Frequent or repeated nosebleeds
• Hearing loss
• Nasal discharge, usually bloody
• Prolonged bleeding
• Stuffy nose

Signs and tests:

The doctor may see the angiofibroma when examining the upper throat.

Tests that may be done include:

• CT scan of the head
• Nasal mucosal biopsy (this can be very dangerous, and should only be done after using CT scan or arteriogram to see the blood supply to the growth)
• X-ray

Treatment:

Treatment is required if the angiofibroma is growing larger, blocking the airways, or causing repeated nosebleeds. In some cases, no treatment is necessary.

Surgery may be needed to remove the tumor. Removal is often difficult because the tumor is not enclosed and may have spread deeply to other areas.

A procedure called embolization may be done to prevent the tumor from bleeding. The procedure may correct the nosebleeds by itself, or it may be followed by surgery to remove the tumor.

Expectations (prognosis):

Although not cancerous, angiofibromas may continue to grow. Some may disappear on their own.

It is common for the tumor to return after surgery.

Complications:

• Anemia
• Pressure on the brain (rare)
• Spread of the tumor to the nose, sinuses, and other structures

Calling your health care provider:

Call your health care provider if you often have nosebleeds.

Prevention:

There is no known way to prevent this condition.
