Giant cell arteritis (GCA) is the most common systemic vasculitis. Ischemic manifestations are well known. In cases of thoracic aortic aneurysms with unknown etiology, GCA is a possible cause. GCA is an inflammation of the lining of the arteries. Most often, it affects the arteries in the head, especially those in temples. For this reason, GCA is sometimes called temporal arteritis or cranial arteritis. GCA frequently causes headaches, jaw pain, and blurred or double vision, less often blindness and chest pain in rare cases [1].
