ABSTRACT
Radiofrequency ablation (RFA) is a popular technique and shows excellent local tumor control and acceptable morbidity. Although RFA is considered much safer than surgical treatment, it is not a complication-free procedure. The most common complications of percutaneous RFA areabdominal hemorrhage, abdominal infection (abscess), biliary tract damage, and ground-pad burns. Laparoscopic RFA (LRFA) is a safe, feasible treatment modality to achieve tumor destruction. LRFA has proven superior to the percutaneous approach for lesions that are difficult or impossible to treat percutaneously. Needle-track implantationafter LRFA is a rare complication in HCCs. We report a case of needle-tract implantation of HCC found in the chest wall, ribs,and diaphragm 11 months after LRFA in a 49-year-old man. Although treatment for needle-track implantation is not well established, the metastatic mass was surgically removed.
