case_images: (a)-(c): Axial
  diffusion-weighted images, b = 1000, demonstrate multiple areas of high signal in
  bilateral frontal and parietal lobes, left occipital lobe, left thalamus, and
  left pons.

case_images: Magnetic resonance imaging (MRI) of the brain (Figure 1) demonstrated bilateral multifocal regions of increased signal on diffusion-weighted imaging in the left pons, left occipital lobe, left thalamus, left and right frontal lobes, and left and right frontoparietal regions.
case_images: 3D maximum-intensity
  projection (MIP) image from a 3D time of flight MRA demonstrates occlusion of
  the right internal carotid artery at its origin (arrow). The vertebral arteries
  are diminutive (arrowheads) and the basilar artery is not visualized.

case_images: fig2
case_images: Magnetic resonance angiography (MRA) of the head and neck without contrast (Figure 2) demonstrated occlusion of the right internal carotid artery (ICA) at its origin without distal reconstitution.
case_images: 3D MIP
  images from a noncontrast 2D time of flight MRA demonstrate restoration of flow
  in the right internal carotid artery and posterior circulation. Residual
  occlusion of the distal right PCA persists (arrow).

case_images: MRA evaluation (Figure 3) revealed resolution of the right ICA thrombus with overall decreased caliber of the vessel compared to the left, and residual irregularity and narrowing at the superior cervical segment.
