Inflammatory aneurysm of arcus aorta with massive hemoptysis.

A 72-year-old woman was admitted to the intensive care unit with a diagnosis of acute coronary syndrome. An aneurysm in the aortic arch was detected in the radiologic investigations. The aortic arch was replaced with a Dacron graft with the patient under total circulatory arrest. A pathology evaluation revealed an inflammatory aneurysm. To date, a few cases of inflammatory aneurysms of the aortic arch have been reported. Unlike the previously reported cases, the aneurysm in our case unexpectedly presented with massive hemoptysis.
