Abstract
We report a case of secondary hemocholecyst following percutaneous liver biopsy. Mirizzi syndrome was suspected based on imaging studies. A 64-year-old man developed right upper quadrant abdominal pain 7 days after liver biopsy done due to alchoholic liver injury. Computed tomography showed a swollen gallbladder and a high density mass measuring 3 cm in diameter on the day of pain onset. Ten days after the liver biopsy, magnetic resonance imaging demonstrated a stenosed common hepatic duct displaced by the swollen gallbladder and the heterogeneous parenchymal mass. The patient underwent a cholecystectomy under a diagnosis of acute cholecystitis and Mirrizi syndrome. Although the gallbladder was enlarged and filled with hemorrhagic fluid, there were no findings indicating inflammation. We diagnosed this case as secondary hemocholecyst following liver biopsy ; this is the first reported case of Mirizzi syndrome that was suspected based on imaging findings. Recently the number of hemobilia and secondary hemocholecyst cases have been increasing due to the increasing number of procedures such as liver biopsy and percutaneous transhepatic bile drainage being done. We discuss the etiology and appropriate treatment of hemocholecyst with respect to the present case.
