Giant cell arteritis (GCA) is the most common systemic vasculitis in the elderly. It is characterized by the involvement of the large vessels, predominantly the extracranial branches of the aorta. There is a close relationship with polymyalgia rheumatica (PMR). The first description of GCA was provided by Sir Jonathon Hutchinson in 1890, who described a patient at the London Hospital who could not wear a hat because of painful red streaks on his head. The painful streaks were thickened temporal arteries with feeble pulsations. The full description of the condition was provided by Bayard Horton in 1932.
