Presentation
Patient known to have hypertension, diabetes and dyslipidemia, presented to the emergency department complaining of dizziness and vertigo for 3 days, associated with blurred vision and gait imbalance.
Patient Data
Selected single images demonstrate an area of T2/FLAIR hyper-intensity with diffusion restriction is noted in the right lateral medulla likely to represent an acute infarction.
Case Discussion
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.
