Evaluate for biliary leak. Status post OLT with perihepatic fluid collections. ABDOMEN:LIVER, BILIARY TRACT: The portal vein and its branches are patent. There is increased biliary ductal dilatation with branching pulmonary defect within the biliary tree compatible with pneumobilia seen on recent CT. No hepatic lesion is identified. Rim-enhancing fluid collection in the gallbladder fossa measures 2.7 x 0.8 cm coronally, from previously 4.0 x 4.2 cm. At 20 minutes hepatobiliary phase, contrast is seen avidly enhancing the biliary system and does not appear to fill the drained collection, suggesting against a biliary leak or fistulous communication. Drainage catheter again noted within the collection.SPLEEN: Mild splenomegaly is redemonstrated.PANCREAS: Fatty involution of the pancreas.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Multiple bilateral simple and proteinaceous cysts, stable from prior exam.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.
Significant interval decrease in size of drained abscess in the gallbladder fossa without evidence of biliary leak or fistula.
