ABSTRACT
Giant cell arteritis (GCA), a relatively common form of vasculitis in the United States and Europe, is also referred to as temporal arteritis, cranial arteritis, and Horton's disease (1-4). It affects persons over 50 years of age and approximately 90% of patients are over 60 years of age when the disease begins (5). Giant cell arteritis involves the cranial branches of the arteries originating from the arch of the aorta most prominently, but is often more generalized (6,7).
