Abstract
A forty-five-year—old woman with a history of arterial hypertension was diagnosed as having a dissection of the ascending aorta progressing toward the descending aorta, where two false lumina were shown on magnetic resonance dynamic and spin-echo imaging and confirmed at autopsy. The other imaging techniques used did not allow a precise visualization of this anomaly. The place of the different imaging techniques in this type of aortic dissection is discussed.
