A Case of Hepatocellular Carcinoma with intradural growth Presenting as Obstructive Jaundice

－Abstract－The incidence of hepatocellular carcinoma presenting as obstructive jaundice is 0.7∼9%. The mechanisms of obstructive jaundice include bile duct invasion by tumor, tumor thrombi, blood clots, direct bile duct compression by tumor, and intraductal tumor growth. We report a rare case of hepatocellular carcinoma with intraductal growth. A 46-year-old woman was admitted due to colicky right upper abdominal pain and jaundice for 4 days. Computed tomography showed dilatation of the left intrahepatic duct, and endoscopic retrograde cholangiography showed a filling defect in the left main intrahepatic duct. We performed a left lobectomy with a Roux-en-Y hepaticojejunostomy. The tumor was diagnosed as a hepatocellular carcinoma with intraductal growth.KeyWords: Hepatocellular carcinoma, Intraductal, Obstructive jaundice서 론간세포암 환자에서 황달은 대부분 간경변증이나 종양의 미만성 침윤에 의한 간기능 부전에 의해 발생하는 경우가 대부분이며, 담관 침범에 의한 폐쇄성 황달로 발현하는 경우는 드믈어 그 빈도가 전체 간세포암의 0.7∼9% 정도로 알려져 있다.
