Description

Wallenberg Syndrome (aka: lateral medullary syndrome or the posterior inferior cerebellar artery syndrome) is a neurological disorder with a variety of symptoms associated with posterior circulation ischemic stroke.

1810 – Alexander Marcet (1770–1822) reproduced the case for the Royal SocietyThe gentleman who is the subject of the following singular case is Dr Vieusseux, an eminent physician of Geneva…whilst in London he was induced to draw up and communicate to the Society the particulars of his own case…‘.
