[Cogan's syndrome--an interdisciplinary diagnostic challenge].

Cogan's syndrome is a rare autoimmune-like disorder characterised by nonsyphilitic interstitial keratitis and Meniere's syndrome-like audiovestibular function disorder. David G. Cogan initially described the syndrome in 1945. In 1980 Haynes et al proposed diagnostic criteria for patients with other ocular symptoms and suggested this to be atypical Cogan's syndrome. We report a case of a 43 year-old woman with atypical Cogan's syndrome. The patient received a cochlear implant prior to diagnosis.
