Giant cell arteritis (GCA) is a systemic immune-mediated granulomatous vasculitis of large- and medium-sized arteries mainly affecting elderly people. Death from GCA alone is rare and usually results of ruptured aorta. In this paper is reported a case of a 83-year-old woman who unexpectedly died during treatment of GCA. Necropsy revealed inflammatory involvement of the coronary arteries with left descendent anterior artery thrombosis, myocardial infarct and rupture of the anterior wall of the left ventricle, as well as hemopericardium and cardiac tamponade. Myocardial infarction leading to sudden death is an exceptional complication of GCA.

Annuloaortic ectasia (AAE) is a clinicopathologic condition with primary or secondary dilatation of the aortic annulus and aneurysm of the proximal thoracic aorta, leading to aortic regurgitation. We herein report an autopsy case of a Japanese 57-year-old male with AAE who died of a cardiac tamponade rupture from the sinus of the right coronary. The wall of the aortic root, particularly that of the sinus of the right coronary Valsalva, underwent extensive fibrosis with loss or fragmentation of the elastic lamina in the medial layer and perforation directly into the pericardial space. The adventitia of the proximal aorta to the aortic arch was diffusely fibrotic with both acute and chronic hemorrhage and chronic inflammatory infiltrate. However, the ascending aortic media was largely intact, except for focal laminar necrosis at the center of the medial layer; no medial cystic necrosis, laminar necrosis, or mesoaortitis/panaortitis was present in the thoracic or abdominal aorta, nor in the main aortic branches, which was suggestive of Takayasu disease and giant cell arteritis. Thus, this patient was diagnosed to have idiopathic AAE with sustained peri-aortic hemorrhage, and he finally died of a cardiac tamponade resulting from an aneurysmal rupture.

Giant cell arteritis is a granulomatous inflammation of large and medium-sized arteries, occurring predominantly in older women. In this case, a 76-year-old woman was hospitalized for examination because of a high C-reactive protein (CRP) level, but nothing remarkable was found on thoracicoabdominal computed tomography (CT) or head magnetic resonanse imaging (MRI). On the 46th day from the first visit, she died suddenly due to cardiac tamponade. On pathological autopsy, we found the cause of death to be acute aortic dissection (Stanford type A) due to giant cell arteritis occurred in the ascending aorta. Histologically, granulomatous vasculitis with giant cells was recognized in the ascending aorta, thoracic descending aorta and abdominal aorta and their branches. Interestingly, similar granulomatous vasculitis was also found in the medium and small vessels of other plural organs, including the heart, liver, uterine corpus, and its appendages. To our knowledge, giant cell arteritis with multiple-organ granulomatous changes has not been reported before. We herein reported a unique autopsy case of giant cell arteritis in a patient not treated with medication.
