SummaryGiant cell arteritis (GCA) is an autoimmune disease characterized by granulomatous inflammation in the wall of medium-sized and large-sized arteries, and it usually occurs in patients over 50 years of age.1) Symptoms are nonspecific, and include fatigue, fever, and headache.2) It is occasionally combined with aortic complications, and ruptures resulting in death. These complications occur as late events, usually several years after diagnosis and often after other symptoms have subsided.3) Physicians should therefore be alert for complications of the large arteries in GCA. Here we present a case of GCA combined with ascending aortic dissection and rupture 3 weeks after diagnosis.

Case ReportA 76-year-old woman was admitted to our hospital because of headache, disturbance of her field of view, jaw claudication, and high fever. Approximately 6 months earlier, she had new-onset headache, abnormality of view, and jaw claudication. One month before admission, her body temperature rose to 39°C. The patient saw a primary care physician a week before admission. Physical examination revealed a Levine grade 3 systolic murmur at the apex, and echocardiographic examination showed a thickened mitral valve and moderate mitral regurgitation. The physician suspected infectious endocarditis and referred the patient to our hospital for further examination.With regard to past history, the patient was receiving antihypertensive drugs. There was nothing of note in her family history, and she had never smoked and had never been abroad. Her body weight had fallen by 15 kg in the previous 6 months due to loss of appetite. Vital signs were stable except for an increase in body temperature (38°C). Systolic blood pressure was 120 mmHg and diastolic blood pressure was 70 mmHg, and there were no crosswise differences. Pulse rate was 90 beats per minute. The bulbar conjunctiva showed neither petechial hemorrhages nor anemia. There was no pain at her temporal lesion and no cervical lymphadenopathy. A pan-systolic murmur was heard at the apex (Levine grade 3), and respiratory sound was clear. There was no edema, petechia, or nodules on her limbs. On the day of admission, an electrocardiogram revealed sinus rhythm (90 beats per min) and no ST-T abnormality. Chest X-rays revealed slightly extended mediastinum. Laboratory data suggested the presence of severe inflammation (Table I).On transthoracic echocardiography, we found thickening of the anterior mitral leaflet and moderate mitral regurgitation. Transesophageal echocardiography showed no evidence of vegetation attached to the valves. We performed 2 sets of blood cultures, and they were sterile. In additional laboratory examinations, cytoplasmic antineutrophil antibody, perinuclear antineutrophil cytoplasmic antibody, and other specific antibodies were all negative, and complement was not decreased. Also, there was no elevation of IgG4. In order to investigate the focus of inflammation...
