A case of mycotic aneurysm of the aorta caused by Klebsiella pneumoniae accompanied by endophthalmitis / 대한내과학회지

ABSTRACT

A mycotic aneurysm is a localized, irreversible arterial dilatation resulting from destruction of the vessel wall by infection. Pathogens causing mycotic aneurysms include Gram-positive and -negative bacteria, mycobacteria, and fungi. Klebsiella pneumoniae is a common pathogen causing urinary tract infections, nosocomial pneumonia, soft tissue infection, pyogenic liver abscesses, and endophthalmitis, while mycotic aneurysms caused by K. pneumoniae are rare. Recently, the number of cases of endogenous K. pneumoniae endophthalmitis associated with K. pneumoniae-induced pyogenic liver abscesses has increased in Southern Asia, but there have been no reports of K. pneumoniae mycotic aneurysms accompanied by endophthalmitis. Here, we report the case of a man who had a K. pneumoniae mycotic aneurysm accompanied by endophthalmitis and, ultimately, lost sight in both eyes. The early diagnosis of associated endophthalmitis requires a high index of suspicion by the physician.
