Case history
A 72-year-old woman of Northern European ancestry presents with partial vision loss in the right eye. She reports bitemporal headache for several weeks, accompanied by pain and stiffness in the neck and shoulders. Review of systems is positive for low-grade fever, fatigue, and weight loss. On physical examination, there is tenderness of the scalp over the temporal areas and thickening of the temporal arteries. Fundoscopic examination reveals pallor of the right optic disc. Bilateral shoulder range of motion is limited and painful. There is no synovitis or tenderness of the peripheral joints. There are no carotid or subclavian bruits, and the blood pressure is normal and equal in both arms. The remainder of the examination is unremarkable.

Respiratory tract symptoms are uncommon but may include cough or sore throat. Rarely, dental pain, tongue pain, or infarction of the tongue may be present.[2]Dinkin M, Johnson E. One giant step for giant cell arteritis: updates in diagnosis and treatment. Curr Treat Options Neurol. 2021;23(2):6.

In addition, over 20% of patients who have symptoms suggestive of polymyalgia rheumatica may have GCA.[6]De Miguel E, Macchioni P, Conticini E, et al. Prevalence and characteristics of subclinical giant cell arteritis in polymyalgia rheumatica. Rheumatology (Oxford). 2024 Jan 4;63(1):158-64.

GCA can rarely present as an unexplained systemic illness or fever of unknown origin with elevated levels of inflammatory markers without headache, jaw claudication, shoulder or hip girdle stiffness, or visual disturbances.
Patients with large-vessel stenoses (approximately 10% to 15% of patients) may present with claudication of (usually) upper extremities, asymmetric blood pressures, or decreased pulses.[7]Bongartz T, Matteson EL. Large-vessel involvement in giant cell arteritis. Curr Opin Rheumatol. 2006 Jan;18(1):10-7.

Rarely, involvement of lower extremity vessels results in leg claudication.[8]Kermani TA, Matteson EL, Hunder GG, et al. Symptomatic lower extremity vasculitis in giant cell arteritis: a case series. J Rheumatol. 2009 Oct;36(10):2277-83.
