Temporal arteritis

Also called Giant cell arteritis, GCA, or Cranial arteritis

Temporal arteritis, also called giant cell arteritis, is a condition where the arteries, especially those at the sides of the head (temples), become inflamed. It mostly affects people over 50 and is linked to polymyalgia rheumatica. Without fast treatment it can cause permanent loss of sight.

What it is

It is treated urgently with high-dose steroids, often before tests are complete. The dose is then slowly reduced over many months.

Other medicines may be added to reduce steroid use. Bone protection and regular checks are part of care.

Common signs

  • A new, severe headache, often at the temples
  • Tender scalp, for example when brushing hair
  • Jaw pain when chewing
  • Double vision or sudden loss of vision
  • Tiredness, fever or weight loss

How it is usually diagnosed

  • Blood tests for inflammation (ESR, CRP)
  • Ultrasound of the temple arteries
  • Sometimes a biopsy of the temporal artery

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Inflammation blood test results
  • Ultrasound or biopsy reports
  • Rheumatology and eye clinic letters
  • Steroid dose schedule

Questions to ask your doctor

  • How long will I need steroids?
  • How will my eyes be monitored?
  • What should I do if symptoms return?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Any change in vision, or a new severe headache with jaw pain or scalp tenderness: get urgent help the same day, call 112 if vision is lost
