Various diseases have been associated with hepatobiliary cysts, such as autosomal dominant polycystic liver disease (ADPLD) and primary bile duct cysts. These cystic lesions may develop in the intrahepatic and/or extrahepatic bile duct wall and correlate with peribiliary gland ectasia on histology [1]. Magnetic resonance imaging (T2 RARE sequence) shows significant intrahepatic and extrahepatic bile duct lesions without clear signs of neoplasia or diffusion-restrictive lesions.
