MRI findings of acute right medullary infarct consistent with lateral medullary syndrome, which is also known as Wallenberg syndrome. It is a clinical syndrome caused by an acute ischemic infarct of the lateral medulla oblongata. This is most commonly due to occlusion of the intracranial portion of the vertebral artery followed by PICA and its branches.

The patient in our case was presented by vestibulocerebellar symptoms which are consistent with the radiological findings.
