Patient History

A 63-year-old man was referred for a magnetic resonance imaging (MRI) study of the chest following an abnormal echocardiogram. The patient had no physical signs or symptoms of disease. He was taking aspirin, an angiotensin-converting enzyme (ACE) inhibitor, and prednisone.

Figure 1 (A, B, C). Magnetic resonance angiographic (MRA) study of the aorta (A) demonstrates an aneurysm with a maximum diameter of 6 cm; relative sparing of the aortic root is seen, terminating in the proximal arch. Double-inversion black-blood MRI (B) study acquired at the level of the left pulmonary artery shows aneurysmal dilatation of the ascending aorta with circumferential thickening (arrow). Fat-suppressed 3D MRI study (C) demonstrates diffuse enhancement of the aortic wall (arrow).
