Giant Cell Arteritis : Clinical
Giant Cell Arteritis (GCA) - Clinical: GCA is a large vessel vasculitis, thought to be of autoimmune origin, usually seen in elderly patients. The most commonly affected are temporal, cerebral, and retinal arteries; however, it can also involve aorta and extracranial carotid artery branches.
The patients present with pain and tenderness in face and scalp, jaw claudication, and even blindness. About 50% of cases develop polymyalgia rheumatica consisting of pain and tenderness involving neck muscles, shoulder girdle, and pelvis.
