Impending rupture of an atherosclerotic aortic aneurysm in an 83-year-old man. The patient had been followed for stable aortic aneurysm for many years and suddenly presented with acute chest pain. a Non-contrast CT demonstrates ballooning of the aorta at the aortic arch. The aortic wall shows haemorrhagic content within the aortic wall (arrow), which suggests an acute process of this event. b Axial CTA depicts bulged dilatation of the aorta on the right side of the aortic arch (arrowheads), which was not depicted on the previous follow-up CT images. c Oblique coronal MPR image demonstrates dilatation of the aorta (arrowheads) with a thickened aortic wall with haemorrhagic content. The aortic lumen shows an eccentric bulge, a sign of impending rupture of an atherosclerotic aortic aneurysm
