Intramural hematoma(IMH) and penetrating aortic ulcer have been increasingly recognized as causes of acute aortic pathology in addition to aortic dissection. The presence of the intimal tear and a flap traversing the aortic lumen is considered to be a most reliable differential point of aortic dissection and IMH. Transesophageal echocardiography(TEE) has become a valuable modality for the diagnosis, prognosis and management of acute aortic syndrome with the unique advantages of portability and the ability to obtain high-resolution real time images. Endovascular Stent-graft placement over the primary entry tear may be an alternative to open surgery because it can close the intimal tear, which leads to thrombosis of the false lumen, excluding flow through the intimal tear and redirecting aortic flow exclusively into the true lumen. We report 88 year-old male with aortic dissection in descending thoracic aorta, successfully treated with endovascular Stent-graft implantation, which was mimicking intramural hematoma by its appearance and subclinical intimal tear diagnosed exclusively by TEE against other imaging studies.
