Figure 4: Abdominal magnetic resonance imaging and magnetic resonance cholangiopancreatography performed in February 2012. (a) T1-weighted and (b) T2WI images. The signal intensity within the cystic mass is stronger than that of simple cysts on the T1-weighted image. In addition, multilocular septal structures and nodular solid components are visible at the base. There is no clear communication with the intrahepatic bile ducts.
