62-year-old male patient status post liver transplant with perihepatic abscess. Evaluate size of abscess and for biliary leak. ABDOMEN:LIVER, BILIARY TRACT: Postsurgical changes from choledochojejunostomy noted. Rim-enhancing fluid collection the gallbladder fossa with drain in place with layering, likely iatrogenic, air currently measures 1.5 x 3.6 cm (series 10 image 34), previously 0.8 x 2.7 cm. At 20 minutes in the hepatobiliary phase, contrast is seen in the biliary system and does not appear to infiltrate the drained collection, suggesting there is no biliary leak or fistulous communication.Branching susceptibility artifact in the intrahepatic biliary system compatible with pneumobilia. Minimal intrahepatic biliary ductal dilatation appear similar compared to prior examination. The portal vein is patent and mildly attenuated at the anastomosis, which is not unexpected. Enlarged lymph node at the porta hepatis is unchanged compared to prior.SPLEEN: Mild splenomegaly, measuring up to 12 cm in craniocaudal dimension.PANCREAS: Atrophic pancreas.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Multiple bilateral simple and proteinaceous cysts, similar compared to prior.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
Mild interval increase in size of collection in the gallbladder fossa with drain in place. There is no definite connection with the biliary system on delayed images.
