Weber syndrome
Introduction
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.
