Intrahepatic cholangiocarcinoma presenting intrabile duct tumor growth: report of a case.
A case of intrahepatic cholangiocarcinoma with intrabile duct tumor growth is presented. A 70-year-old female with prolonged obstructive jaundice and cholangitis was diagnosed with a mass lesion in the left lobe of the liver accompanied by an intrabile duct component which caused hilar bile duct obstruction. Percutaneous transhepatic biliary drainage (PTBD) was performed via three routes with intensive care of the drainage catheters over a 2-month period to alleviate jaundice and cholangitis. Extended left hepatic lobectomy with combined resection of extrahepatic bile duct and regional lymph nodes were carried out curatively. Macroscopically, a tumor formed a 8 x 6 cm mass with a scalloped margin in the left lobe and had an intraductal component with a round smooth surface protruding from the lumen of the left hepatic duct into the common bile duct. The histologic type of the tumor was well differentiated tubular adenocarcinoma. The intraluminal tumor grew expansively without invasion to the bile duct wall. The postoperative course was uneventful and the patient has remained in good health without recurrence for 1 year and 3 months since surgery. This case report discusses a rare extension pattern in ICC and the management of malignant hilar obstruction during radical surgery.
