Aortic dissection is uncommon with high mortality rate if untreated. We report a challenging case of long segment aortic dissection in which the dissection type was very difficult to identify due to limitations of the available imaging studies. 66-year-old male presented to us with 3 days history of chest pain and difficulty breathing. He is known to be hypertensive. In the emergency room, patient has systolic blood pressure >190. Chest X-ray showed widening of mediastinum. CT angiography of

Transthoracic and Trans-esophageal echocardiography revealed a partially calcified intimal flap in the distal portion of the arch and in the descending thoracic aorta suggestive of Stanford type B aortic dissection. Medical treatment started, and repeated CT angiography was obtained and it confirmed type B aortic dissection. One week after discharge, patient was readmitted with severe neck pain and difficulty breathing. CT chest without contrast showed grossly stable appearance of type A dissection consistent with the first CT angiography. Cardiothoracic surgery immediately reevaluated the situation and recommended surgical intervention. ARTICLE INFO
