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

Figure 3 Seventy-two-year-old female patient with malignant intraductal papillary mucinous neoplasm of the bile duct (case 3). A: Axial image of enhanced computed tomography in the portal venous phase showed extensive intra- and extrahepatic bile duct dilatation with multiple hydra-like protrusions (arrows); B: Dilation appeared hyperintense (arrows) with diffusion-weighted imaging; C: Hypointense (arrows) with T2-weighted imaging; D: Gadolinium-ethoxybenzyl-diethylenetriamine-pentaacetic acid-enhanced magnetic resonance imaging in the hepatobiliary phase revealed no hyperintense bile with distribution of the contrast agents in the dilated bile duct, indicating a large amount of mucin retention, which was confirmed by endoscopy.
