Abstract
A 62-year-old woman was hospitalized in our department due to recurrent fever after sphincteroplasty performed for acute cholangitis caused by Lemmel's syndrome 40 days previously at another hospital. Ultrasound, computed tomography and hepatic angiography demonstrated solid focal liver mass in the right lobe, and cholangiocellular carcinoma was suspected. Right lobectomy was performed and resected specimen showed empyema in the locally dilated bile duct in the posterior segment, and multiple small abscesses surrounding the bile duct. The cause of these liver abscesses may be due to stenosis and dilatation of intrahepatic bile duct which was over-looked before initial sphincteroplasty. In some early pyogenic liver abscess, differential diagnosis from solid liver mass is required.
