Vasculitis & polymyalgia rheumatica
Low incidence of late-onset giant cell arteritis during the first year in patients with polymyalgia rheumatica–a repeated imaging study
Authors' conclusion
This study is the first to demonstrate a low incidence rate of late-onset GCA in PMR patients within the first year, employing repeated imaging to exclude GCA at baseline and diagnose GCA during follow-up.
