title: Masked giant cell arteritis.
abstract: BACKGROUND
  Giant cell arteritis (GCA) is the most common vasculitis in the western world and often presents as a diagnostic problem for general practitioners. Prompt diagnosis and treatment is important to prevent potential irreversible complications, with a favourable outcome.
  
  
  OBJECTIVE
  This article discusses a case of GCA presenting with mild anaemia, weight loss and high erythrocyte sedimentation rate.
  
  
  CONCLUSIONS
  Anaemia and high inflammatory markers are common blood abnormalities encountered in the elderly population. Even though anaemia as a primary presentation of GCA has been well documented in the past, our case highlights the importance of considering this as a differential diagnosis in the community. Ways of assessing the so-called 'masked GCA' which may enable a better awareness of the diversity of this disease, is also discussed.
