A rare Danish case of Yersinia pseudotuberculosis pyogenic liver abscess

Area of Science:

• Microbiology
• Infectious Diseases
• Hepatology

Background:

• Yersinia pseudotuberculosis is a Gram-negative bacillus typically causing enterocolitis and terminal ileitis.
• Liver abscesses are uncommon manifestations of Yersinia pseudotuberculosis infections.

Observation:

• A Danish patient presented with a 6-week history of intermittent fever, fatigue, and weight loss.
• The patient was diagnosed with multiple pyogenic liver abscesses attributed to Yersinia pseudotuberculosis.

Findings:

• This case represents the first reported instance of Yersinia pseudotuberculosis-induced multiple pyogenic liver abscess in Denmark.
• The patient's clinical presentation included prolonged, intermittent fever, fatigue, and significant weight loss.

Implications:

• This case expands the known spectrum of Yersinia pseudotuberculosis disease presentation.
• Successful management involved a combination of percutaneous drainage and broad-spectrum antibiotic therapy (piperacillin/tazobactam and ciprofloxacin).
• Early diagnosis and appropriate treatment are crucial for managing rare hepatic manifestations of Yersinia pseudotuberculosis.
