The natural history of an aortic dissection is either endothelialization of the false lumen forming a so-called double-barrelled aorta, or thrombosis of the sack leading to fibrosis and scarring. Complete healing of an aortic dissection is extremely rare, and has to our knowledge only been reported once in vivo. Here we report a second case of spontaneous resolution of an aortic dissection, disclosed by contrast medium enhanced computed tomography.
