Giant-cell aortitis: an unusual case of Bentall operation

Noninfectious ascending aortitis is a very rare cause of ascending aortic aneurysm. We report a case of the truly fortuitous finding of this rare condition in a 67-year-old man operated on for an ascending aortic aneurysm associated with dystrophic aortic valve regurgitation. Intraoperative inspection revealed dissection of the aorta just above the left main coronary artery. A modified Bentall operation was performed. The pathological diagnosis was giant cell arteritis.
