Giant cell arteritis (GCA) is a rare cause of ascending aortic aneurysm. We present here a 50-year-old patient who was clinically diagnosed with annuloaortic ectasia. She was successfully treated by Bentall′s operation. Histopathologically, the findings were of GCA. GCA should be suspected when older women presented with aortic aneurysm and continued surveillance of remaining aorta is necessary.
