Case Report of Cogan Syndrome
Semih Aydoğan*, Nuray Akyol*, Tamer Demir*.
Cogan syndrome is an inflammatory vascular disease with involvement of eye and ear. Cogan syndrome consists of
interstitial keratitis associated with vestibuloauditory dysfunction. The disease has a predilection for large and
medium sized blood vessels. Early diagnosis of Cogan syndrome is important because prompt treatment of the
cochlear symptoms with systemic steroids may prevent permanent and profound deafness. A case of Cogan
syndrome in chronic stage is represented in this report.
