Figure 2 Choledochal involvement of a pancreatic mass. A and B: Coronal T2 WI and coronal magnetic resonance cholangiopancreatography images. The dilated choledochal duct (circle) abruptly narrows bluntly (white arrow) and continues narrowly in a long segment more distally (two-headed arrow). Contour irregularities (serrated lines) are seen on the distal walls of the choledochal duct; C and D: Post-treatment axial and coronal computed tomography images of the same patient show an irregularly bordered, hypodense, heterogeneous, solid mass lesion (circle) in the head of the pancreas, stent material extending from the duodenum to the pancreas (orange arrow), and dilated intrahepatic bile ducts (white arrow).
