Article Figures & Data

Figures

  • FIGURE 1.
    FIGURE 1.

    Spot images obtained during 99mTc-disofenin scanning show lack of radiotracer activity in small bowel. Activity in gallbladder (arrow) is first seen on delayed 24-h image.

  • FIGURE 2.
    FIGURE 2.

    Axial (A) and coronal (B) contrast-enhanced CT images of abdomen show diffusely enlarged, sausage-shaped pancreas with loss of lobulation and presence of low-attenuation peripancreatic halo (thin arrows). Common bile duct is dilated, with abrupt change in caliber (thick arrow).

  • FIGURE 3.
    FIGURE 3.

    Coronal thin-slab MR cholangiopancreatography image (A) and spot image from endoscopic retrograde cholangiopancreatography (B) confirm focal stricture of distal common bile duct (arrows).

  • FIGURE 4.
    FIGURE 4.

    Maximum-intensity-projection image (A) and coronal thin-slab MR cholangiopancreatography image (B) obtained 10 mo after initiation of treatment with systemic steroids show resolution of biliary stricture.
