GCA is a vasculitis of medium and large vessels. It rarely occurs before the age of 50 years. In one study, headache was present in 86% of cases.1 However, the headache may be progressive, spontaneously subside, or wax and wane in intensity.2 Carotid artery tenderness has been reported in 7% of GCA cases.3 Temporal artery biopsy remains the gold standard for the diagnosis of GCA.4 CT and magnetic resonance angiography can be used to demonstrate large vessel involvement.5 , 6 Ultrasonography7 and PET-CT8 are also being evaluated as possible diagnostic tools, but are not yet reliable testing modalities.
