Abstract:
In an 80-year-old patient with syncope, a markedly tortuous descending thoracic aorta produced images on transesophageal echocardiography which were suggestive of an intimal flap caused by dissection. A magnetic resonance aortogram clearly showed that the trans-esophageal echocardiogram was a false positive. In addition, multiplanar reconstructed images of the magnetic resonance aortogram through the tortuous descending thoracic aorta could reproduce images similar to that seen by transesophageal echocardiography. Because transesophageal echocardiography has become a popular imaging modality for the detection of aortic dissection, it is essential for echocardiographers to be aware of possible pitfalls which may create false positive findings.
