Abstract
PDF
- A 69-year-old man patient was hospitalized by confused mentality. He had chronic hepatitis B virus infection
and was diagnosed with liver cirrhosis 20 years ago. Abdominal CT showed about 2×1 cm sized polypoid mass
with mild arterial enhancement at the S4 of liver, causing moderate dilatation of the left IHBD. In the CTHA-AP,
intraductal mass was hyperattenuated at arterial phase and washed out at portal phase. Celiac angiography
revealed nodular tumor staining correlating to intraductal mass on CT. In MRCP and ERCP, a polypoid lesion was
noted at the orifice of left main intrahepatic duct. The patient was treated with cyber-knife for 3 days with 3600
cGy. In follow up CT after 2 month of cyber-knife treatment, there was regression of previously noted left IHBD
dilatation and no definite enhancing intraductal mass.
