Figure 2 Magnetic resonance imaging showing multiple stones and an oval-shaped tumor in the common bile duct. A: Magnetic resonance imaging (MRI) with cholangiopancreatography showing multiple signal voids in the common bile duct (CBD) reflecting tiny stones; B: T2-weighted MRI image showing an oval-shaped tumor 20 mm in diameter in the lower CBD with high-intensity signal (left row); and a diffusion-weighted image showing a mass lesion in the lower CBD with a round high-intensity signal (right row).
