Cogan syndrome associated with mesenteric vascular insufficiency

Nonsyphilitic interstitial keratitis and deafness was first described as a distinct entity by Cogan in 1945. For years thereafter, it was believed to involve only the ocular and aural systems. It is gradually becoming apparent that the syndrome can also include other organ systems by affecting their blood supply. A patient with diagnosed Cogan syndrome subsequently developed mesenteric vascular insufficiency that was surgically corrected. This report lends more support to the belief that nonsyphilitic interstitial keratitis with deafness is only one manifestation of a more generalized vascular disease.
