What is it?

What is giant cell arteritis?

Giant cell arteritis causes the arteries of the scalp and neck to become red, hot, swollen, or painful. The arteries most affected are those in the temples on either side of the head. These arteries narrow, so not enough blood can pass through.

It is important that you get treatment right away. Otherwise, the arteries could be permanently damaged. There is also a risk of blindness or stroke.

If you have giant cell arteritis, your doctor should also look for signs of another disorder, polymyalgia rheumatica. These conditions often occur together.

Is there a test for giant cell arteritis?

To diagnose you with giant cell arteritis, your doctor will:

  • Ask you about your medical history.
  • Give you a physical exam to see if the arteries in your temples are swollen, tender to the touch, and have a reduced pulse.
  • Take a small section of the artery in your temple to examine it under a microscope.

How is it treated?

How is giant cell arteritis treated?

Giant cell arteritis is treated with medications, such as prednisone. You will probably take high doses of the medicine for about one month. Your doctor will slowly reduce the dose, which may cause some symptoms to come back. After a while, symptoms usually go away completely, and the doctor can stop the prednisone altogether.

You should report any symptoms to your doctor so that you can be treated early. This will help prevent serious problems such as permanent vision loss and stroke.
