An Elderly Case of Giant Infected Liver Cyst That Decreased Dramatically without Percutaneous Aspiration

Abstract

A 70-year-old woman was referred to our hospital for treatment of cholelithiasis. A giant liver cyst (6cm in diameter) had been diagnosed three years earlier. On admission, she had low grade fever and hepatomegaly. High values were observed for WBC (9900/μl), CRP (8.9mg/dl), GPT (45IU/l), ALP (1399IU/l), γ-GTP (333IU/l) and LAP (249IU/l). The diagnosis of infected liver cyst (8cm in diameter) was made based on contrast-enhanced CT scan. Endoscopic retrograde cholangiopancreaticography showed no communication between the cyst and the intrahepatic bile duct. She was successfully managed with antibiotics and discharged without percutaneous aspiration the cyst. On abdominal CT scan 4 months after the discharge, the liver cyst had decreased dramatically in size (1cm in diameter). The patient remains healthy without symptoms.
