We report a case of hepatocellular carcinoma located just below the right hemidiaphragm that was diagnosed as having hepatitis C virus–related cirrhosis 12 years ago. Although the lesion was not clear on conventional sonography, it was clearly defined on CO 2 ‐enhanced sonography, allowing safe and accurate radiofrequency ablation. By combining radiofrequency ablation with transcatheter arterial chemoembolization, extensive cauterization and complete tumor necrosis were obtained with only 1 session of treatment. The patient had no serious adverse effects and has shown no recurrence during 35 months of follow‐up. © 2006 Wiley Periodicals, Inc. J Clin Ultrasound, 2007.
