The contrast-enhanced computed tomographic scan of the patient’s neck revealed normal enhancement of the vascular structures. There was a retropharyngeal course of the right internal carotid artery (ICA) (Figure 1 and Figure 2, arrows), which was otherwise of normal diameter and appearance (Figure 1). There was an associated elevation of the right posterior pharyngeal wall, without mucosal lesions. The usual course of the ICA was observed on the left side, where the artery (arrowhead) was found in the carotid space just anterior to the jugular vein (Figure 2).
