CXR has overall limited sensitivity [...] for thoracic aortic aneurysm, and
alone cannot be used to exclude acute or chronic aortopathy
Calcification or tortuosity of the ascending, arch, and descending thoracic aorta may be visualized, but this is a non-specificific finding in the elderly.
Opacification of the aortico-pulmonary window, enlargement of the thoracic aorta, increased mediastinal width, displacement of trachea from midline, or obscured/irregular aortic margin may indicate thoracic aortic aneurysm, dissection, or rupture. Displaced intimal calcium and pleural effusion may indicate dissection.
