[Liver abscess caused by Klebsiella pneumoniae in diabetic patients]. / Absceso hepático por Klebsiella pneumoniae en pacientes diabéticos.

ABSTRACT

Pyogenic liver abscess are macroscopic collections of pus within the hepatic parenchyma after a bacterial infection. These infections are usually polymicrobial in nature, and in most occasions due to biliary tract diseases or cryptogenetic in origin. Monomicrobial hepatic abscess caused by Klebsiella pneumoniae are uncommon lesions in western countries. These lesions are associated with underlying diseases, particularly diabetes mellitus, and are frequently complicated with septic metastasis. We report here three cases of monomicrobial liver abscess caused by Klebsiella pneumoniae in diabetic patients, without septic metastasis and a favourable outcome.
