ABSTRACT
Even though radiofrequency ablation of single liver malignancy is effective and safe procedure, however major complication such as large biloma or abscess can occur rarely. In addition, just drainage procedure sometimes cannot improve these complications accompanying the onset of a biliary fistula. We report a case that was complicated by a biliary-biloma fistula with abscess formation after successful percutaneous radiofrequency ablation of single liver metastases from cholangiocarcinoma and radiologic interventions to treat successfully persistent biliary fistulas with refractory liver abscess.
