Weber's syndrome
Overview
Overview
Weber’s Syndrome (superior alternating hemiplegia) is characterized by the presence of an oculomotor nerve palsy and contralateral hemiparesis or hemiplegia.
It is caused by midbrain infarction as a result of occlusion of the paramedian branches of the basilar artery.[1]
It should not be confused with Sturge-Weber syndrome or Klippel-Trenaunay-Weber syndrome.
