Atypical Cogan’s Syndrome: A Case Report

Abstract

Cogan’s Syndrome is a rare autoimmune disease that presents with multi-system involvement including the eyes and ears. It is typically characterized by attacks of vertigo resembling Meniere, sensorineural hearing loss and interstitial keratitis. Ocular findings may vary widely, other than interstitial keratitis in the manner of atypical form which is less frequently seen and has a less favourable prognosis. Here, a 52-year-old male patient with atypical Cogan’s Syndrome is reported. In Cogan’s Syndrome, especially if diagnosis is delayed, hearing diminishes progressively and deafness usually occurs despite therapy, while ocular findings usually respond to topical therapy and persistent blindness does not occur. Persistent sensorineural hearing loss can be prevented by early diagnosis and immediate high dose systemic steroid administration with other immunosuppressive agents if required.
