Magnetic resonance cholangiopancreatography revealed a defect in the proximal common hepatic duct, dilation of the distal common hepatic duct, and marked irregularity and thread-like narrowing of the proximal common bile duct (Figure 1).

Endoscopic retrograde cholangiopancreatography showed evidence of a malignant-appearing stricture at the level of hepatic bifurcation with significant proximal dilation (Figure 2).
Papanicolaou stain of a fine-needle aspiration sample of the pancreatic head mass. Note the significant nuclear pleomorphism, nuclear crowding, prominent nucleoli, and 3-dimensional cellular arrangement.
