Successful endoscopic procedures for intraductal papillary neoplasm of the bile duct: A case report

Figure 1 Images of cholangioscopic examination, ERC, MRCP and abdominal CT. A: Cholangioscopic examination performed in 1999. A multilobulated papillary tumor was seen protruding into the common bile duct; B: ERC performed in 1999; C: ERC performed in 2008. The extrahepatic bile duct became more dilated in 2008 than in 1999. A polypoid filling defect (arrow heads) could be detected in the distal bile duct; D: MRCP in 1999; E: MRCP in 2004. Cystic lesions connected to the intrahepatic bile ducts of the left liver became enlarged in 2004; F and G: Abdominal CT in 1999; H and I: Abdominal CT in 2004. Intra- and extrahepatic bile ducts became dilated in 2004. A mass in the distal bile duct (arrow heads) and a cystic lesion in the left liver were enlarged in 2004, compared with those in 1999.
