A 100 year-old female was admitted to our hospital because of fever and anorexia. After admission, right hypochondralgia and slight liver dysfunction appeared. Ultrasonogram revealed a giant hepatic cyst with sludge echo and a few small hepatic cysts. CT-scan showed enlargement of the cyst containing two layers of fluid, which had been detected four years previously. Ultrasonically guided drainage of the cyst was performed and pus was obtained through the drainage tube. Since patient's general condition improved completely, the tube was removed eight days after drainage. Although the cyst remained 5 cm in diameter at that time, it disappeared nine months after removal of the drainage tube. Destruction of the epithelium of the cyst wall caused by infection was suspected to be the reason for the disappearance of this large cyst. Since ultrasonically guided drainage is an easy and safe procedure, it should be the first choiced for treating infected hepatic cysts, even in advanced aged.
