The terms "giant cell arteritis" and "temporal arteritis" are sometimes used interchangeably, because of the frequent involvement of the temporal artery. However, other large vessels such as the aortacan be involved.[44] Giant-cell arteritis is also known as "cranial arteritis" and "Horton's disease".[45] The name (giant cellarteritis) reflects ...
Arteritis. Arteritis is a vascular disorder characterized by inflammation of the walls of arteries, [1] usually as a result of infection or autoimmune responses. Arteritis, a complex disorder, is still not entirely understood. [2] Arteritis may be distinguished by its different types, based on the organ systems affected by the disease. [2]
Giant cell arteritis (GCA) is the most common type of systemic vasculitis in adults. Polymyalgia rheumatica (PMR), headache, jaw claudication, and visual symptoms are the classic manifestations; however, 40% of patients present with a variety of occult manifestations. [9]
Vasculitis is a group of disorders that destroy blood vessels by inflammation. [ 2 ] Both arteries and veins are affected. Lymphangitis (inflammation of lymphatic vessels) is sometimes considered a type of vasculitis. [ 3 ] Vasculitis is primarily caused by leukocyte migration and resultant damage.
Aortitis is most commonly seen in patients with syphilis, autoimmune vasculitis (giant cell arteritis, Takayasu's arteritis), polymyalgia rheumatica, and rheumatoid arthritis. [2] IgG4-related disease has more recently been identified as a cause of aortitis, and also as a cause of periaortitis (inflammation surrounding the aorta). [3]
Granulomatosis with polyangiitis (GPA), previously known as Wegener's granulomatosis (WG), [1][2][3][4][5] after the German physician Friedrich Wegener, is a rare long-term systemic disorder that involves the formation of granulomas and inflammation of blood vessels (vasculitis). It is an autoimmune disease and a form of vasculitis that affects ...
A giant cell (also known as a multinucleated giant cell, or multinucleate giant cell) is a mass formed by the union of several distinct cells (usually histiocytes), often forming a granuloma. [ 1 ] Although there is typically a focus on the pathological aspects of multinucleate giant cells (MGCs), they also play many important physiological roles.
Takayasu's arteritis. Takayasu's arteritis (TA), also known as aortic arch syndrome, nonspecific aortoarteritis, and pulseless disease, [2] is a form of large vessel granulomatous vasculitis [3] with massive intimal fibrosis and vascular narrowing, most commonly affecting young or middle-aged women of Asian descent, though anyone can be affected.
