Computed tomography showing dilated ascending aorta with flap of proximal dissection. A. Computed tomography – 3-D reconstruction image: dilated ascending aorta is visible with a flap of proximal dissection along the distance of visualized vessel. B. Computed tomography – transverse plane zoom image: at the level of aortic root a true and false lumina of the vessel are visible, separated by a flap of dissection. C. Computed tomography – tangenital plane: showing ascending aorta and partially false lumen with an intimal flap of proximal aortic dissection.
