Mal aigu des montagnes et crise de Ménière

: A professional mountain guide experienced an attack of vertigo at high altitude (4,000 m). Clinical data and the results of functional tests, were consistent with an attack of Meniere's disease. The physiopathological changes noted at high altitudes, and known as acute mountain sickness, are described. A hypothesis is suggested concerning the mechanism triggering this attack of Meniere's disease at high altitude.
