FP1232 : Lateral medullary syndrome-case series.

Dr.Mrunmayi Jeste, M21554

Lateral medullary syndrome (LMS), also known as Wallenberg syndrome or PICA syndrome, constitutes about 2% of ischemic strokes in brain. Seventy-five to ninety percent of LMS occurs due to large vessel disease in the vertebral artery, but it may also occur due to a posterior inferior cerebellar artery occlusion. Major symptoms are ataxia, dysphagia, dysphonia, diplopia, dizziness, Horner syndrome, nystagmus, lateropulsion and sensory loss over ipsilateral side of face and contralateral side of trunk. There are a few variants of lateral medullary syndrome in which there is association of hemiplegia. Babinski-Nageotte syndrome is Wallenberg syndrome with contralateral hemiplegia, while Opalski syndrome is Wallenberg syndrome with ipsilateral hemiplegia. We report a three-patient case series with diplopia, nystagmus and hemianesthesia with varied other symptoms. Early identification of such syndromes is mostly a clinical diagnosis and can prevent further complications.
