Traumatic carotid artery pseudoaneurysm. a Axial CT angiogram image demonstrates irregularity of the left common carotid artery (arrowheads) after stab wound to the neck. The left internal jugular vein (black arrow) is also injured. Note medialization (paralysis) of the left vocal fold (white arrow), due to concomitant vagus nerve injury. b Sagittal curved reformatted CT angiogram image better demonstrates the focal pseudoaneurysm (arrowheads) of the left common carotid artery, proximal to the bifurcation
