Bacterium Tracks Discovered In Arteries With Giant Cell Arteritis (Temporal Arteritis)

Giant cell arteritis, also called temporal arteritis or cranial arteritis, is a serious disease that is characterized by inflammation of the walls of the blood vessels (vasculitis). The vessels affected are the arteries (hence the name "arteritis"). The diagnosis is confirmed with a biopsy of an artery, usually an artery on the side of the scalp called the temporal artery.

Polymyalgia rheumatica (PMR) is a disorder of the muscles and joints of older persons. It is characterized by pain and stiffness, affects both sides of the body, and involves the shoulders, arms, neck, and buttock areas.

Giant cell arteritis occurs in 10-15% of patients with polymyalgia rheumatica. The age of affected patients with these conditions is over 50 years. The onset of giant cell arteritis may be years before, after, or without accompanying polymyalgia rheumatica.
