We report a case of liver abscess caused by Aspergillus and Enterococcus faecium in a patient with acute myeloid leukemia. As far as we know, this is the first case of hepatic aspergillosis in Korea. After remission induction chemotherapy, the female patient presented with abdominal pain and was found to have liver abscess. The patient was treated with antibiotics against E. faecium, which was isolated from the abscess drainage. However, the therapeutic response was unsatisfactory and a left lateral sectionectomy of the liver was conducted after 21 days of treatment. The liver tissue showed typical pathologic findings of aspergillosis and voriconazole was administered. Allogeneic hematopoietic stem cell transplantation was performed successfully after 4 months. The possibility of aspergillosis should be considered when an immunocompromised patient with hepatic abscess poorly responds to the use of broad spectrum antibiotics.
