Two cases of pyogenic liver abscess due to Klebsiella pneumoniae in immunocompetent children

다국어 초록 (Multilingual Abstract)

Pyogenic liver abscess (PLA) can be caused by bacteria entering the liver via the portal vein or primary bacteremia, or it can be cryptogenic. Recently, Klebsiella pneumoniae has been increasingly found as a PLA pathogen. PLA due to this bacterium often leads to formation of extrahepatic abscesses. The treatment of choice is dual therapy with insertion of percutaneous catheter drainage and antibiotic therapy. We report 2 cases of PLA due to K. pneumoniae in immunocompetent children. We successfully treated patient 1 with percutaneous catheter drainage for 18 days and 6-week course of antibiotic therapy. Patient 2 was treated with percutaneous needle aspiration and antibiotic therapy for the same period. In both patients, the PLAs showed the ultrasound-confirmed resolutions after the dual therapy.
