Abstract
Intrahepatic cholangiocarcinoma (ICC) is often unresectable when it is found. Its recurrence rate after operation is high, and, therefore, its prognosis is poor. A case of ICC with invasion to the duodenum surviving for more than two years after operation is reported.
A 63-year-old woman was found to have a low-density area in segment 4 of the liver. She was followed for two years, and the size of the tumor did not change. She was found to have a duodenal submucosal tumor on gastrointestinal endoscopy, and CT showed a tumor in segment 4 of the liver that was invading to the duodenum. The tumor diameter was 33 mm. The patient underwent liver resection of segment 4, partial duodenectomy, and lymphadenectomy. The pathological diagnosis was ICC. Liver metastases were found 9 months later, and the patient was treated by radiofrequency ablation and transarterial chemoembolization. She remains with liver metastases at 28 months after the operation. Invasion to other organs together with very slow growth is very rare in ICC.
