Transition from classic aortic dissection to aortic intramural hemorrhage - A case report

A 64-year-old man was hospitalized with chief complaints of chest and back pain. A diagnosis of Stanford type A aortic dissection with a false lumen e xtending from the ascending to the descending aorta was made based on the r esults of computed tomography (CT). A CT obtained the following day showed resolution of the false lumen and increased brightness of the aortic wall, typical of aortic dissection with intramural hemorrhage. Although previous studies have described a gradual transition from aortic intramural hemorrha ge to aortic dissection with a false lumen, there are no reports of the tra nsition from an aortic dissection with a false lumen to the intramural hemo rrhage type of aortic dissection. This patient is of interest when consider ing the pathogenesis of aortic dissection with intramural hemorrhage and th e relationship between the intramural hemorrhage and false-lumen types of a ortic dissection.
