Prior echocardiographic examination showed dilated aortic root with suspicious intimal flap. CT scan was requested to rule out dissection.

The aortic root is dilated at the level of the sinuses of Valsalva with a diameter of 4.7 cm.
There is mild fusiform dilatation of the proximal descending thoracic aorta distal to the aortic isthmus. This aortic configuration is consistent with an aortic spindle. It measures 3.2 cm in diameter.
The innominate and left common carotid arteries share a common origin from the aortic arch (bovine aortic arch).
There is no demonstrable aortic dissection.
