Also known as periarteritis nodosa. A rare but potentially serious disease, probably caused by a disturbance of the immune system (see IMMUNITY). Prolonged fever and obscure symptoms referable to any system of the body are associated with local areas of in?ammation along the arteries, giving rise to nodules in their walls. Large doses of CORTICOSTEROIDS, coupled with IMMUNOSUPPRESSANT treatment, usually curtail the disorder. Recovery occurs in about 50 per cent of cases.... polyarteritis nodosa
