Intraductal papillary neoplasm of the left intrahepatic bile duct found during early gastric cancer treatment: A case report

Figure 1 Abdominal computed tomography and magnetic resonance cholangiopancreatography. A-C: Computed tomography revealed a dilation of the common bile duct and left hepatic bile duct and atrophy of the left lobe of liver (orange arrows); D-F: Magnetic resonance cholangiopancreatography showed dilation of the common bile duct and left hepatic bile duct.

Figure 2 Endoscopic ultrasonography and endoscopic retrograde cholangiopancreatography images. A: Endoscopic ultrasonography showed obvious common bile duct dilation; B: Endoscopic ultrasonography showed high echo flocculent in the left bile duct lumen; C: Endoscopic retrograde cholangiopancreatography showed common bile duct dilation and multiple filling defects in the mid-proximal segment of the common bile duct; D: Intrabile duct ultrasound mixed high echo flocculent was observed in the mid-proximal segment of the common bile duct.

Figure 3 EyeMaxÔ direct visualization system. A-C: Papillary eminence was found in the secondary branching bile duct of left outer lobe; D: Papillary neoplasm was located in the secondary bile duct of left outer lobe of liver (the gross specimen), and abundant gelatinous mucus was observed in the excised specimen.
