Cogan syndrome was initially suspected in view of the characteristic interstitial keratitis, fluctuating sensorineural hearing loss, and episodic vertigo.
When a review of the patient's ophthalmologic examination revealed that he suffered from recurrent iritis and not interstitial keratitis or uveitis, the diagnosis of Cogan syndrome was questioned.
