Typically gallbladder [[adenocarcinomas]] appear as large heterogeneous masses, which may have engulfed [[gallstones]] or areas of [[necrosis]]. Patchy moderate contrast enhancement is usually seen.
 
Features of advanced disease include:
 
*Intrahepatic biliary dilatation
*Invasion into adjacent structures
*[[Lymphadenopathy]]
*Peritoneal carcinomatosis
*Hepatic and distant metastases<ref>http://radiopaedia.org/articles/gallbladder-adenocarcinoma</ref>
