Giant cell arteritis (GCA) is a systemic vasculitis affecting mainly large and medium-sized arteries. GCA sometimes involves the aorta and its major branches and causes aortic dissection as a rare complication. We have experienced an autopsy case of aortic dissection due to GCA. The patient was an 87-year-old Japanese woman with Stanford type A aortic dissection who died 7 days after admission. Two years previously she had been diagnosed as having abdominal aortic aneurysm and undergone endovascular aneurysm repair (EVAR). Although she had no characteristic symptoms of GCA, autopsy revealed marked granulomatous inflammation in the dissected area and coronary arteries. Active arteritis was evident not only in the arteries of the upper extremity but also those in the lower extremity. Granulomatous inflammation was not evident in the aneurysm. The aortic dissection might have been an initial manifestation of GCA. We report the regions of GCA extension and its histology in detail.

D013700 Giant Cell Arteritis A systemic autoimmune disorder that typically affects medium and large ARTERIES, usually leading to occlusive granulomatous vasculitis with transmural infiltrate containing multinucleated GIANT CELLS. The TEMPORAL ARTERY is commonly involved. This disorder appears primarily in people over the age of 50. Symptoms include FEVER; FATIGUE; HEADACHE; visual impairment; pain in the jaw and tongue; and aggravation of pain by cold temperatures.
