Abstract

Billiary cystadenoma and cystadenocarcinoma are rare neoplasms of the biliary ductal system. The authorspresent 2 cases of biliary cystadenoma and 3 cases of cystadenocarcinoma. The typical sonographic apearance ofthese tumors is a large intrahepatic gloular or ovoid thickwalled cystic mass which often containes multipleseptations with papillary growth and solid portion. Low-level internal echoes may be seen within the cystic mass.The characteristic CT findings of these tumors are multiloculated cystic mass, thick sepatations with papillaryprojection sand solid portion within the cystic mass. Angiographical characteristics of these tumors arehypovascular mass with frequent abnormal clusters of tumor vessels within the walls on arterial phase andaccumulation of contrast material along the wall or internal septation on delayed film.
