Temporal arteritis, the second type of giant cell arteritis, is also a chronic, inflammatory disease involving mid- to large-sized arteries.[9] Temporal arteritis has a higher incidence in people of Scandinavian descent.[9] However, the incidence rate differs based on population, region and races.[9] Temporal arteritis is not uncommon in North America.[9] The incidence rate is around 0.017% for individuals over 50 years of age.[9]
