Giant cell (temporal) arteritis diagnosed following upper limb claudication.

Giant cell arteritis or temporal arteritis occurs almost exclusively in people over 50 years of age. It classically presents with new onset temporal headache, scalp tenderness and jaw claudication. Proximal muscle pain and stiffness is often present because of frequent association with polymyalgia rheumatica. In most cases, the erythrocyte sedimentation rate is markedly elevated. Uncommon presentations include systemic symptoms and symptoms related to large artery involvement. We report a case of giant cell arteritis without symptoms related to the temporal artery, diagnosed angiographically following upper limb claudication and confirmed by temporal artery biopsy.
