| arteritis | <pathology> Inflammation of an artery. See: cranial arteritis, giant cell arteritis. (20 Jun 2000) |
| arteritis nodosa | <radiology> Necrotizing vasculitis of medium-sized arteries, usually in male adults, associated with hepatitis B antigen, kidney: most frquently involved organ (85%), multiple small intrarenal aneurysms, aneurysms may disappear (thrombosis) or appear in new locations, arterial narrowing and thrombosis (chronic/healing stage), multiple small cortical infarcts, associated with hypertension and renal failure, chest involvement (70%), cardiomegaly/pericardial effusion (14%), wedge shaped/round peripheral infiltrates simulating PE (14%), interstitial lower lung field pneumonitis, also may involve liver (66%), mesenteric vessels (50%), skeletal muscle (39%), skin (20%) (12 Dec 1998) |
| arteritis obliterans | Obliterating endarteritis, an extreme degree of endarteritis proliferans closing the lumen of the artery. Synonym: arteritis obliterans, obliterating arteritis. (05 Mar 2000) |
| brachiocephalic arteritis | Giant-cell arteritis seen in older adults; characterised by inflammatory lesions in medium sized arteries, most commonly in the head, neck and/or shoulder girdle area; lesions include fragmented elastin, macrophages, and giant cells. Erythrocyte sedimentation rate is usually markedly elevated. Visual loss can occur. (05 Mar 2000) |
| giant cell arteritis | <pathology> An inflammatory condition of the temporal artery. It is a serious chronic vascular disease, characterised by inflammation of the walls of the blood vessels (vasculitis). The age of affected patients is usually over 50 years of age. It most often involves the carotid artery system, and can lead to blindness or stroke. It can be diagnosed by biopsy of an artery, but there is often a false negative result. Elevation of the erythrocyte sedimentation rate is typical. Treatment is with high dose steroids. Common symptoms include headaches and tenderness over the temple (temporal artery). Can be associated with polymyalgia rheumatica. See: polymyalgia rheumatica. Synonym: cranial arteritis, temporal arteritis (20 Jun 2000) |
| rheumatic arteritis | Arteritis due to rheumatic fever; Aschoff bodies are frequently found in the adventitia of small arteries, especially in the myocardium, and may lead to fibrosis and constriction of the lumens. (05 Mar 2000) |
| rheumatoid arteritis | Coronary arteritis associated with rheumatoid arthritis; aortitis with aortic valve incompetence accompanying ankylosing spondylitis may be related. (05 Mar 2000) |
| granulomatous arteritis | giant cell arteritis |
| coronary arteritis | Inflammation of any or all of the layers of coronary artery walls. (05 Mar 2000) |
| cranial arteritis | <pathology> An inflammatory condition of the temporal artery.

| Heubner's arteritis | Inflammation of arteries within the circle of Willis secondary to chronic basal meningitis from tubercle bacillus or particular fungi such as Cryptococcus, Histoplasma, or Coccidiodes. (05 Mar 2000) |
| Horton's arteritis | giant cell arteritis |
| neurocranial granulomatous arteritis | A small vessel giant cell arteritis which affects only intracranial blood vessels, of unknown aetiology, and with diverse clinical manifestations, including those seen with an involving cerebral tumour, and with a lower grade meningitis, leading to infarction of one portion of the cerebrum or cerebellum.
