CT
Axial non-contrast
Axial C+ arterial phase
Cranial non-enhanced computed tomography (NECT) and contrast-enhanced computed tomography (CECT) show patchy low-density areas on both cerebral hemispheres, representing ischemic strokes. There is a crescent-shaped hyperattenuating focus on the right internal carotid arteries (ICAs), representing intramural hematomas, with an intimal flap and double-lumen; Occlusion of the left ICA is hyperdense on NECT and do not opacify on CECT, corresponding to an intraluminal thrombus.
Impression: These findings favored bilateral dissections of ICAs.
