Carotidynia. a Axial time of flight image demonstrates a rind of soft tissue surrounding the left internal carotid artery (LIC). Note the normal appearance of the right internal carotid artery (RIC). b Coronal post-contrast T1-weighted image shows avid enhancement of the rind of soft tissue (arrows) surrounding the left internal carotid artery (LIC). Note the normal appearance of the right internal carotid artery (RIC). c Follow-up approximately 4 months later, coronal post-contrast T1-weighted fat-saturated image shows decreased thickness of the rind of soft tissue (arrows)
