A 64-year-old man was diagnosed as having a hepatocellular carcinoma (HCC) which was 10mm in diameter. It was revealed by computed tomography (CT), magnetic resonance imaging (MRI) and angiography, however, it could not be detected by conventional ultrasonography.For the purpose of detecting the lesion during the operative procedure, we used CO2-ultrasonography (CO2-US). CO2-US successfully demonstrated the site of the lesion both preoperatively and intraoperatively.CO2-US is an efficacious and less invasive imaging modality for thoraco or laparoscopic microwave coagulo-necrotic therapy (MCN), when the lesion can not be detected by conventional ultrasonography.
