male, 74 year(s)
 
 
  • Figure 1
    Peribiliary cysts

    Enhanced Computed Tomography (CT) examination revealed multiple confluent cysts on both sides of the portal tracts, mimicking biliary duct dilatation.

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: Education; Special Focus: Cysts;
     
     
  • Figure 2
    Peribiliary cysts

    Subcostal US examination showed multiple round or tubular anechoic lesions around the large portal tracts mimicking bile duct dilatation.

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: Education; Special Focus: Cysts;

    (a, b) MRI reveals multiple T1 hypointense, T2 hyperintense round structures coursing along the portal tracts, with a diameter ranging from 0.2 to 2 cm, consistent with peribiliary cysts.
