Caroli’s disease, also known as congenital communicating cavernous ectasia of the biliary tree, is a rare autosomal recessive developmental abnormality characterized by saccular dilatation of the intrahepatic bile ducts. The magnetic resonance (MR) images shown here are from a 21-year-old man who presented with jaundice, abdominal pain, and fever for 5 days. On clinical examination, he had tenderness in the right hypochondrium. Laboratory parameters showed elevated direct serum bilirubin, alkaline phosphatase, AST, ALT, and leukocyte count. Axial T2-weighted MR revealed hyperintense dilated cystic structures of varying sizes that communicate with the biliary tree. Hypointense multiple intraluminal filling defects due to intraductal lithiasis were seen (Fig. 1). MR cholangiography demonstrated the pathognomonic feature of saccular dilated and nonobstructed intrahepatic bile ducts that communicate with
