Giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) are relatively common diseases of the middle aged and elderly. Their cause is unknown, and their incidence increases with age (1). The two conditions are genetically and clinically linked, although there are differences in their pathophysiology (2). They are systemic diseases frequently associated with constitutional symptoms including fevers, malaise, and weight loss. Both conditions may present with pain and stiffness of the neck and shoulder girdle muscles. GCA may also present with ear, nose, and throat manifestations.
