A 57-year-old man with poorly controlled diabetes mellitus (DM) was admitted to our hospital with a four-day history of fever, chills, and mild right upper quadrant pain. On physical examination, mild tenderness in the right upper quadrant of the abdomen was observed. Laboratory data showed leukocytosis (15.3×109/L) with hyperglycemia and minor changes in liver values. A contrast-enhanced computed tomography (CT) scan of the abdomen revealed a large gas-forming abscess measuring 12 cm×11 cm×9 cm in the right lobe of the liver (Figure 1). The patient underwent CT-guided percutaneous catheter drainage and was given broad-spectrum intravenous antibiotics and insulin. Klebsiella pneumoniae was cultured from both blood and pus. With a gas-forming pyogenic liver abscess (GFPLA) diagnosis, he received six weeks of antibiotic therapy and had a satisfactory response to the medical treatment without any complications.
