Overview
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.[1] 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.[2]
