Differentiation Between Biliary Cystic Neoplasms and Simple Cysts of the Liver: Accuracy of CT

Abstract

Upstream bile duct dilatation, lesion location at the left hepatic lobe, fewer than three coexistent cysts, and THAD were found to be highly suggestive CT findings for the differentiation of biliary cystic neoplasms from simple hepatic cysts. Radiologists' performance was significantly improved with the knowledge of these highly suggestive CT criteria.
