45-year-old male with history of ERCP. Evaluate for biliary pathology and fluid reaccumulation. LIVER: Patent portal vein with antegrade flow. Large fluid collection in the right hepatic lobe measures 19.6 x 14.6 cm, not significant changed. The more medial right hepatic lobe lesion seen on prior CT are not clearly visualized on this study.BILIARY TRACT: Interval placement of a biliary stent with intrahepatic biliary duct dilation is less conspicuous compared with recent CT allowing for differences in technique.

SPLEEN: Unremarkable in size and echogenicity. KIDNEY: No hydronephrosis, nephrolithiasis, or solid mass. OTHER: No significant ascites.
