32-year-old patient with acute dissection of both internal carotid arteries and the right vertebral artery (the same patient as in the previous image).

(A, B) Reformatted contrast-enhanced MRA of the neck shows a long stenosis from acute dissection of cervical segments of both the right (arrow) and left (dashed arrow) internal carotid arteries and the V3 segment of the right vertebral artery (arrowhead).
