Differentiating biliary cystadenomas from benign hepatic cysts: Preliminary analysis of new predictive imaging features

Published:November 03, 2017DOI:


      • Hepatic cysts and biliary cystadenomas are difficult to differentiate by imaging
      • The relationship of internal septations to the cyst wall can better differentiate hepatic cysts from biliary cystadenomas
      • Septations arising perpendicular to a flat cyst wall may be the best feature to determine the need for surgical treatment



      To identify performance of imaging features in differentiating hepatic cysts from biliary cystadenomas of the liver.


      25 pathologically confirmed hepatic cystic lesions (hepatic cysts or biliary cystadenomas) were evaluated retrospectively and predetermined imaging features assessed for performance in differentiation.


      Any septation which arose from a cyst wall without external indentation had a very high association with biliary cystadenoma, while the presence of a thick septation had only a moderate association.


      The relationship between septations and the wall of the cystic lesion performed better than previously reported features including thick septations.
