FIG1
CTA demonstrated an abrupt cutoff of the contrast at the origin of the left vertebral artery (Figure 1), with faint contrast filling and irregular lumen seen within the V3 and V4 segments of the left vertebral artery, suggestive of VAD. Magnetic resonance imaging (MRI) and magnetic resonance angiogram (MRA) were both performed after three days and showed high T2 signal intensity involving the inferior part of the left cerebellum (Figure 1) and crescent-shaped T2 signal intensity in the fourth segment of the left vertebral artery (Figure 2).
Crescent-shaped high T2 signal intensity within segment 4 of the left vertebral artery. Blue arrows: the dissected part of the fourth segment of the left vertebral artery (LVA); picture A: upper cross-section magnetic resonance imaging (MRI) with contrast of the vertebral artery; picture B: lower cross-sectional MRI with contrast of the LVA
