Liver abscess due to Yersinia bacteremia in a well-controlled type I diabetic patient.

Yersiniae enterocolitica, a gram negative rod-like organism, causes terminal ileitis and mesenteric adenitis in adolescents and adults. Some forms present with liver and spleen abscesses and have worse prognosis. We report a type 1 diabetic patient with a liver abscess mimicking metastatic liver disease who was successfully treated with percutaneous drainage and antibiotic administration; culture from blood was positive for Yersinia enterocolitica, but drainage material from the liver abscess did not yield a positive result for Yersinia enterocolitica. Although the prognosis is not good in such cases, with high mortality rates, our patient recovered from the disease with appropriate treatment.
