Treatment of liver abscess caused by Klebsiella pneumoniae with multi-site infection: a case report

This medical case report describes a patient with a pyogenic liver abscess caused by Klebsiella pneumoniae who was eventually diagnosed with invasive Klebsiella pneumoniae liver abscess syndrome. Invasive Klebsiella pneumoniae liver abscess syndrome has permanent morbidity, poor quality of life, and lacks warning signs. Despite the complexity of the condition, the patient received effective treatment and the abscess was successfully managed. Through this case, we propose that invasive Klebsiella pneumoniae liver abscess syndrome caused by hypervirulent Klebsiella pneumoniae should be considered for patients with diabetes and fever in the emergency department. Targeted intravenous antibiotics and percutaneous drainage of the abscess are key to the treatment of invasive Klebsiella pneumoniae liver abscess syndrome.
