Figure 2. MR angiography of the neck, chest, abdomen, and pelvis.

Image A: Significant dilation of the ascending aorta with thickening of the aortic wall (red arrow). Image B: The carotid and vertebral arteries show no evidence of stenosis, obstruction, or flow alterations. Stenosis of the distal right axillary artery at the level of the quadrilateral space, aneurysmal dilation of the ascending aorta, and enhancement of the descending aortic wall are represented in fluid-sensitive sequences (red arrow). Image C (sagittal view): Aneurysmal dilation of the ascending aorta along with mild pericardial thickening (red arrow). Image D: Normal evaluation of the abdominal system.
