Figure 1  The pathological result suggestive of IPNB (hematoxylin-eosin × 400).

Figure 2 Abdominal enhanced computed tomography and magnetic resonance imaging + magnetic resonance cholangiopancreatography (enhanced) examination. A and B: The initial diagnosis of a cystic solid lesion in the left lobe of the liver with dilatation of the distal intrahepatic bile ducts. Cholangiocarpal cystadenoma was ruled out, and a magnetic resonance enhancement examination was recommended; C-E: Presence of cystic and solid lesions in the left hepatic lobe and dilation of the left intrahepatic bile duct, indicative of intraductal papillary neoplasms of the bile duct.
