title: [A Case of Intrahepatic Cholangiocarcinoma with Invasion to the Transverse Colon and Gallbladder, Forming an Intra-Tumor Abscess].
abstract: An 81-year-old man was referred to our institution for evaluation of high fever and a liver tumor that had been detected by ultrasonography. Computed tomography revealed a low-density mass with peripheral ring-like enhancement in S5 of the liver. The liver mass was in contact with the gallbladder, and the boundary between the mass and the gallbladder was unclear. On the suspicion of liver abscess, percutaneous transhepatic drainage was performed. The cavity of the abscess communicated with the gallbladder. Because the cavity had no tendency to reduce in size, we performed surgical resection under a preoperative diagnosis of liver abscess or primary liver carcinoma invading to the gallbladder. Intraoperative findings revealed a liver tumor invading the transverse colon and gallbladder. Subsegmentectomy of S4a and S5 of the liver combined with gallbladder and transverse colon resection was performed. Histopathological findings indicated the growth of a mass forming type intrahepatic cholangiocarcinoma with invasion to the transverse colon and gallbladder, and the pathological stage of the tumor was pT3N0M0, fStage Ⅲ. Thus far, the patient is alive without recurrence 9 months after surgery. Here, we report an extremely rare case of intrahepatic cholangiocarcinoma that invaded other organs and was associated with an intra-tumor abscess.
