Abstract
Background: Radiofrequency thermal ablation (RFTA) has become a popular
method of unresectable liver tumor ablation. However, its side effects
should be paid attention to. Case Report: A 76-year-old woman was found with
an 8.4 × 6.9 cm subcapsular mass in the left lateral liver lobe. She had
cirrhosis with active hepatitis C. Well-differentiated hepatocellular
carcinoma (HCC) was diagnosed based on fine needle aspiration biopsy (FNAB)
of the liver mass. Later she was treated with ultrasound-guided percutaneous
RFTA using an expandable-type electrode. Contrast-enhanced computer
tomography (CT) suggested that the necrosis of the tumor was complete. Every
3 months, she had a follow-up, consisting of clinical and abdominal CT
examinations. One year after treatment, a 3-cm soft tissue mass was found in
the upper abdominal wall. The mass was resected and it was diagnosed as
metastatic HCC. Conclusion: This case indicated that percutaneous RFTA was
effective in local control of large HCC. However, the diagnostic FNAB, or
percutaneous RFTA itself, may result in needle-track tumor seeding.
