Inflammatory bowel disease imaging: Current practice and future directions

Figure 1 Extraintestinal and extraluminal manifestations of inflammatory bowel disease depicted on imaging. A: Primary sclerosing cholangitis depicted on magnetic resonance cholangio-pancreatography evidenced as intermittent beading and structuring of the intrahepatic bile ducts; B: Penetrating Crohn’s disease depicted on computed tomography as enhancing fistulous tracks (arrows) of an enterocolonic fistula, with associated abscess formation (asterisk) in the adjacent iliacus musculature.
