CT

There are no specific imaging features that permit reliable differentiation of biliary cystadenoma from cystadenocarcinoma.

• The CT attenuation of the fluid component in a biliary cystadenoma varies depending on the fluid content.
• Higher attenuation may indicate recent hemorrhage.
• Calcifications that may be present in the septa or cyst wall are typically more apparent with CT than other imaging modalities.
• Septa may enhance with contrast material.

Biliary cystadenomas range in size from 3 to 40 cm, and can be either unilocular or multilocular. Unfortunately there are no specific imaging features that permit reliable differentiation of biliary cystadenoma from biliary cystadenocarcinoma. As is the case with ultrasound, the appearance of the cyst fluid on CT is variable depending on its composition. It can range from that of water (HU = 0) to quite hyperattenuating if the cyst has been complicated by recent hemorrhage.

Calcifications of septa or cyst wall may be seen. Additionally the septa may enhance following administration of contrast.
