Figures

Figure 1.
Figure 1. Brain MRI at 3 hours after clinical onset. (A, B) DWI and ADC map showed an acute lesion in the left lower midbrain tegmentum. (C, D) T1-hyperintense lesions were found in the BA (arrow). (E, F) T2-weighted imaging identified flow void sign of the BA at the upper and middle pontine levels (arrowhead).
Figure 2.
Figure 2. Brain MRA showed tapered occlusion of the BA at the middle pontine level. Arterial diameters were irregular in the left VA and BA. The intracranial right VA was absent. (A) Antero-posterior view. (B) Lateral view.
Figure 3.
Figure 3. Brain DWI at 7 hours after clinical onset. (A) The midbrain lesion was enlarged. (B, C) New alternating lesions were found in the left upper and right middle pons.
