Traumatic aortic dissection is most commonly caused following sudden deceleration injury. It most commonly involves descending thoracic aorta (DTA) and is associated with high mortality and morbidity if not treated urgently. Confirmation of diagnosis often requires contrast-enhanced computed tomography (CECT) or magnetic resonance imaging (MRI), which is time consuming, expensive, and often not available at many health-care facility. Transesophageal echocardiography (TEE) is equally efficient to CECT and MRI in diagnosing aortic dissection. It may also provide additional information that can be very useful for the management of the patient. In some cases, the likelihood of error in the diagnosis of such a critical condition with normal cardiovascular variations is expected. Herein, we describe a case with primary diagnosis of aortic dissection that led to final diagnosis of an aortic shelf that medically managed with a good long-term prognosis. In patients suspected to aortic dissection due to any cause, the specialized evaluation using the most accurate and sensitive tools is strongly recommended to discriminate normal vascular variations from major vascular defects requiring emergent surgical interventions.
