Gd-EOB-DTPA-enhanced magnetic resonance imaging for bile duct intraductal papillary mucinous neoplasms

Figure 2 Fifty-two-year-old male patient with cystic intraductal papillary mucinous neoplasm of the bile duct (case 2). A: Coronal image of contrast-enhanced computed tomography; B: Gadolinium-ethoxybenzyl-diethylenetriamine-pentaacetic acid-enhanced magnetic resonance imaging (Gd-EOB-DTPA-enhanced MRI) in the portal venous phase showed extensive biliary and aneurysmal dilatations of the right intrahepatic bile duct, with multiple significantly enhanced masses within the lumen (black arrows); C: Gd-EOB-DTPA-enhanced MRI also showed a contrast-filling defect within the common bile duct (white arrows), suggesting the presence of mucin; D: Multiple planar reconstruction of images acquired in the hepatobiliary phase showed a dilated left intrahepatic bile duct with good contrast filling (black arrows). The contrast filling was incomplete in the right intrahepatic and common bile ducts (white arrows).
