[Spontaneous echocontrast, recorded by transesophageal echocardiography in type III aortic dissection].

Spontaneous echo contrast has been described in cardiac chambers and large vessels during decreased blood flow. We report on a patient with type III aortic dissection and spontaneous echos in the false lumen of the thoracic aorta. Both aortic dissection and spontaneous echos were verified by transesophageal echocardiography but not by transthoracic.
