Intralabyrinthine haemorrhage following cocaine consumption

Abstract

The origin of cochleovestibular deficits remains hypothetical, a viral attack or a circulatory disorder being the two most frequently reported hypotheses. We report the case history of a patient suffering from a cochleovestibular deficit after consumption of cocaine, a drug known for its vascular effects. The MRI scans were compatible with an intralabyrinthine haemorrhage. To our knowledge, this is the first case of cochleovestibular deficit due to an intralabyrinthine haemorrhage following cocaine consumption.
