Percutaneous liver biopsy is valuable for making the diagnosis and follow-up of many liver diseases. Complications after ultrasonography-guided liver biopsy are rare, but a few serious complications have been reported. We report here on a 43-year-old man with acute cholangitis and gallbladder hematoma secondary to hemobilia; these occurred 4 days after performing ultrasonography guided percutaneous liver biopsy for the evaluation of multiple liver nodules.
