Figure 2 Imaging of case 1. A: Computed tomography revealed left parietal infarction (ellipse); B: Computed tomography angiography examination revealed tapering occlusion of the Internal carotid artery (ICA) suggestive of ICA dissection (arrow); C and D: Magnetic resonance imaging (T1W-VISTA sequence) demonstrated an intimal intramural hematoma extending to the intracranial section (arrows); E: Duplex ultrasonography examination revealed an intimal flap and significant narrowing of the lumen secondary to the equal-echoic mural hematoma (ellipse); F: Carotid artery digital subtraction angiography showed tapering occlusion of the left ICA just distal to the carotid bifurcation (Rat tail sign) (arrow). ACA: Anterior cerebral artery; CCA: Common carotid artery; ECA: External carotid artery; MCA: Middle cerebral artery.
