재발한 혼합 간세포 담관상피암종 및 저혈관성 간세포암종 동시 절제 1예

Abstract

Liver cancer is more complex to treat compared to cancers in other organs, since liver function should be considered. In addition, only a few patients can be applied curative treatment due to advanced stage at diagnosis. Therefore, early stage detection is important and has been increased through screening and surveillance programs using image modalities recently. However, it is still difficult to diagnose small or hypovascular hepatocellular carcinoma (HCC) even using advanced image modalties. In particular, hypovascular HCCs do not show arterial contrast enhancement which is a typical finding of HCC on computed tomography (CT) and magnetic resonance imaging (MRI). Those also account for a considerable portion of early HCC. We present 54 yearsold man who had recurrent hypervascular and hypovascular nodules on three phase CT and gadoxetic acid-enhanced MRI. The nodules were removed by surgical resection and confirmed as combined hepatocellular-cholangiocarcinoma and well differentiated HCC respectively. (J Liver Cancer 2017;17:94-99)
