Atypical Cogan Syndrome Mimicking Acute Rheumatic Fever.

ABSTRACT

Cogan syndrome is a syndrome of non-syphilitic interstitial keratitis associated with vestibuloauditory deficits. We report a 10 year-old male child who presented with fever, acute polyarthritis, and unilateral red eye and was diagnosed as acute rheumatic fever. Subsequently unilateral hearing loss was detected and the child was diagnosed to have atypical Cogan syndrome
