Spectrum of mucin-producing neoplastic conditions of the abdomen and pelvis: Cross-sectional imaging evaluation

Figure 10 Intraductal papillary mucinous neoplasm of the bile duct in a 58-year-old woman. A: Contrast-enhanced CT image shows severe dilatation of the left intrahepatic ducts without visible intraductal mass. Note a small stone in the dilated intrahepatic duct (arrowhead); B: Coronal T2-weighted RARE MR image shows dilatation of the intrahepatic and extrahepatic ducts. Note the hypointense intraductal mass (arrow) in the left intrahepatic duct; C: Endoscopic retrograde cholangiogram image shows a filling defect (arrow) within the marked dilated extrahepatic bile duct, due to mucin; D: Coronal gadoxetic acid-enhanced T1-weighted MR image obtained at 60 min post-injection shows contrast-filled bile duct with an elongated, low signal intensity lesion (asterisk), which represents mucin; E: Endoscopy image reveals mucin leaking from the papilla. CT: Computed tomography; RARE: True rapid acquisition with relaxation enhancement; MR: Magnetic resonance.
