Wedge-shaped T2 hyperintensity in the right lateral posterior aspect of the medulla. Area is showing diffusion restriction.
Lack of arterial flow in the right vertebral artery, indicative of occlusion.
Scattered bilateral supratentorial T2 hyperintensities.

The symptoms of the lateral medullary syndrome include vestibulocerebellar symptoms, autonomic dysfunction and ipsilateral bulbar muscle weakness.
