[Cogan's syndrome revealed by haemorrhagic glairous diarrhoea].

INTRODUCTION

Cogan's syndrome is defined by the combination of non syphilitic interstitial keratitis and inner ear dysfunction, similar to Meniere's disease.

OBSERVATION: Cogan's syndrome was revealed by haemorrhagic glaireous diarrhoea in a 21 year-old woman whose medical history included Hirschsprung's disease. Cerebral MRI revealed viral-like bilateral neuritis of the eighth cranial nerve, never described in the literature before. The auditory and visual disorders regressed after treatment with corticosteroids.

CONCLUSION

The early diagnosis of Cogan's syndrome permits the cure of the visual and auditory and notably inner ear symptoms with corticosteroid therapy.
