RESUMEN
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. DISCUSSION: 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.
