Specific histopathologic findings included the presence of giant cells (51%), fragmentation of the internal elastic lamina (41%), intimal thickening (33%), and predominantly mononuclear leukocyte infiltration (32%). Histopathologic interpretation of definite vasculitis was independently associated with giant cells (odds ratio [OR] 151.8 [95% confidence interval (95% CI) 60.2\u2013551.6]), predominantly mononuclear leukocyte infiltration (OR 11.8 [95% CI 5.9\u201324.9]), and fragmentation of the internal elastic lamina (OR 3.7 [95% CI 1.9\u20137.4]). A halo sign on temporal artery ultrasound and luminal damage of large arteries on angiography were significantly associated with presence of giant cells (OR 2.6 [95% CI 1.1\u20136.5] and OR 2.4 [95% CI 1.1\u20135.2], respectively).
