7-year-old spayed female Domestic Short Hair

2015 Image Interpretation Session - Case 7

  • Diagnosed 3 years previously with IBD.
  • Diagnosed with mild diffuse chronic lymphocytic cholangiohepatitis 1 year previously after elevations in liver enzymes were detected. Liver parenchyma at that time was normal on ultrasound though dilation of the intra and extrahepatic biliary system was noted.
  • Cat has been managed for chronic biliary tract infections (diagnosed via cholecystocentesis and cultures). Most recent culture yielded antibiotic resistant bacterial infection.
  • Clinically normal, liver values returned to normal. Here for repeat ultrasound and considerations for intervention.

  • Persistent biliary distension on multiple ultrasounds (always worse at the common bile duct).
  • Suspect that this is a congenitally dilated anomaly with secondary infections.
  • Diagnoses: Choledochal Cyst
  • Dilation resolved, but the cat continued to have cholangiohepatitis and positive bile cultures.
