    First CT scan performed in another hospital with 5mm collimation
     

    The aortic arch appears almost normal even if the beam-hardening artefacts from the superior vena cava disturb the image.

     
    Area of Interest: unknown; Imaging Technique: First CT scan performed in another hospital with 5mm collimation;

    At a lower level the beam-hardening artefacts are less apparent and the aortic arch seems normal.

     
    Area of Interest: unknown; Imaging Technique: First CT scan performed in another hospital with 5mm collimation;

    At the level of the tracheal carena the profile of the thoracic aorta is strange and not does not appear round. The lack of contrast medium inside the vessel makes it more difficult to assess the disease.

    There is a clear modification of the profile of the aortic arch with two flaps coming into the lumen.

     
    Area of Interest: unknown; Imaging Technique: Spiral CT at 3mm collimation in the same patient;

    At the level of the tracheal carena the profile of the thoracic aorta is not rounded.

     
    Area of Interest: unknown; Imaging Technique: Spiral CT at 3mm collimation in the same patient;

    At the level of the pulmonary artery bifurcation it is possible to see a clear dissection.

     
    Area of Interest: unknown; Imaging Technique: Spiral CT at 3mm collimation in the same patient;

    The MPR along the sagittal plane displays clearly the aortic transection starting at the isthmus and determining a pseudoaneurysmatic modification.
