[Cochleovestibular syndrome disclosing dolicho-ectasis of the basilar trunk and vertebral artery].

The authors present a case of a cochleovestibular syndrome with a scanner showing a calcified dolico-ektasis of the basilar truncus and the left vertebral artery. The patient had typical Ménière's disease symptomatology. A retrolabyrinthic diagnosis with substantial recruitment was indicated by the results of the audio-vestibular explorations (stapedius reflex, electroculography, early brainstem evoked response, electrocochleography). The electrocochleography with glycerol test indicated labyrinthic hydrops. Finally, some reflections on the role of neurovascular problems in the pathogeny of some cochleovestibular syndromes are put forward.
