Abstract
A 56-year-old female without previous hepatobiliary disease developed a severe obstructive cholestasis following E. coli urinary tract infection with septicaemia. Liver biopsy showed cholangitis and a unique abnormality of almost all the interlobular bile ducts; the epithelium was irregular with polymorphic, angular, and hyperchromatic or pyknotic nuclei. Some ducts were ectatic , others narrowed due to protrusion of proliferating epithelium. In some areas the ducts were blurred or completely destroyed. Cholangitis or granulomas were, however, not present. Abnormal interlobular bile ducts have to our knowledge not previously been described in septicaemia. The lesion is morphologically distinguishable from other types of abnormal bile ducts. It is considered to be caused by endotoxaemia and seems to be reversible. The cholestasis may be due to endotoxic alteration of biliary secretion, bacterially induced inspissation of bile, and/or mechanical obstruction to the bile duct lesions.
