Insights

A 70-year-old woman with an infected liver cyst was successfully treated with antibiotics alone. The large cyst significantly reduced in size, resolving symptoms and avoiding invasive procedures.

Area of Science:

  • Hepatology
  • Infectious Diseases
  • Medical Imaging

Background:

  • A 70-year-old female presented with cholelithiasis and a history of a giant liver cyst.
  • The patient exhibited symptoms of infection, including low-grade fever and hepatomegaly.

Observation:

  • Laboratory results revealed elevated white blood cell count, C-reactive protein, and liver enzymes (GPT, ALP, gamma-GTP, LAP).
  • Contrast-enhanced CT scan confirmed an 8 cm infected liver cyst with no communication to the intrahepatic bile duct.

Findings:

  • The infected liver cyst was successfully managed non-surgically with intravenous antibiotics.
  • Follow-up CT scan at 4 months showed a dramatic reduction in cyst size to 1 cm.

Implications:

  • This case highlights the potential efficacy of antibiotic therapy as a primary treatment for infected liver cysts.
  • Conservative management may obviate the need for invasive procedures like percutaneous aspiration or surgery in select cases.
