Although higher doses of steroids are required to suppress inflammation in GCA, patients with isolated PMR usually show rapid response to low doses of corticosteroids [3]. Most patients with isolated PMR then withdraw steroids after 12 yrs [3], but up to one-third of patients have a more chronic, relapsing course requiring low doses of corticosteroids for
