title: Liver abscess formation after hepatic chemoembolization for metastatic pancreatic neuroendocrine tumor.
abstract: Hepatic chemoembolization is an effective treatment of unresectable hypervascular hepatic tumors, but history of bilioenteric anastomosis is a major risk factor for liver abscess due to the retrograde enteric bacterial contamination. We report a case of culture-negative liver abscess developed after hepatic chemoembolization for a metastatic pancreatic endocrine tumor, and discuss the pathogenesis of liver abscess formation. We also present a potential pitfall for the prophylactic antibiotic therapy in a patient with a history of bilioenteric anastomosis. This is the first report of a culture-negative liver abscess caused by hepatic chemoembolization for a metastatic pancreatic endocrine tumor.
