CT scans performed before and after liver biopsy. There is a change in diffuse internal density of the common bile duct status post-biopsy secondary to hemobilia.
Pre-biopsy: Common bile duct is normal in size (status post cholecystectomy) and density.
Post-biopsy: Common bile duct has new diffuse internal hyperdensity status post liver biopsy compared to prior CT performed one week prior.
