Temporal or giant cell arteritis is an inflammation of medium and small extracranial vessels that may result in ocular ischemia, an aortitis followed by aortic dissection and peripheral limb ischemia. It should be considered a medical emergency due to the seriousness of end organ damage, in particular visual symptoms. While the presentation may be nonspecific, the presence of a tender temporal artery mandates a temporal artery biopsy. High-dose steroids should be begun the moment the diagnosis is considered and only withdrawn once it has been excluded. A gradual tapering of the steroid dose should occur over at least 1 year, with the consideration of the use of steroid-sparing agents if iatrogenic steroid complications occur. Careful monitoring of the response both clinically as well as with serial inflammatory markers is required.
