Temporal arteritis with giant cell aortitis, coronary arteritis, and myocardial infarction.
Extracranial giant cell arteritis occurs in 10% to 15% of patients with temporal arteritis and polymyalgia rheumatica. Aorta and its major branches are most often involved and death may result from an unsuspected ruptured aortic aneurysm or aortic dissection. Involvement of coronary arteries by giant cell arteritis resulting in death from myocardial infarction is extremely rare. This article describes one such case: an 84-year-old man who died of acute myocardial infarction with the unexpected autopsy finding of giant cell aortitis and coronary arteritis, and who, three years earlier, had sudden onset of bilateral blindness and biopsy-proven temporal arteritis.
