Radiofrequency ablation (RFA) may be used to treat either benign or malignant tumors of the liver. Complications are relatively rare, with the most common being pyogenic liver abscess formation. Risk factors for pyogenic liver abscess formation include Child-Pugh class B or C cirrhosis, biliary tract disease, diabetes mellitus, and preexisting biliary diversion. Differentiating sterile post-ablative necrosis from abscess formation may be difficult on imaging as air may be considered a normal post-ablation finding. Treatment of pyogenic liver abscesses includes drainage and antibiotics targeting the most common organisms. This case presents a 71-year-old female with none of the above risk factors who developed a pyogenic liver abscess after undergoing RFA for a solitary liver metastasis secondary to biopsy-proven colonic adenocarcinoma. She was successfully treated with antibiotics and an indwelling percutaneous drain.
射频消融（RFA）可用于治疗肝脏的良性或恶性肿瘤。并发症相对少见，最常见的是化脓性肝脓肿形成。化脓性肝脓肿形成的危险因素包括Child-Pugh B级或C级肝硬化、胆道疾病、糖尿病以及既往存在的胆道改道。在影像学上区分无菌性消融后坏死与脓肿形成可能较为困难，因为空气可能被视为消融后的正常表现。化脓性肝脓肿的治疗包括引流以及针对最常见病原体的抗生素治疗。该病例为一名71岁女性，无上述任何危险因素，在因经活检证实的结肠腺癌继发的孤立性肝转移接受RFA治疗后发生了化脓性肝脓肿。她通过抗生素和留置经皮引流管成功治愈。
