Biliary growth of colorectal liver metastasis: Case report and review of the literature

Abstract

Introduction: Intrabiliary growth of colorectal liver metastasis determines their capability of dissemination and relapse. Case report: 65-year-old woman underwent sigmoidectomy (2011) and left hepatectomy due to liver metastases affecting the bile tract (2014). In 2020 she developed a 2cm tumour in the union of both hepatic ducts. Cholangiocarcinoma was suspected so resection of the main bile duct, the caudate lobe and lymphadenectomy were performed. On immunohistochemical examination, colorectal liver metastasis was confirmed. Conclusions: Liver metastases should be considered as the most likely diagnosis when bile duct dilatation or intrabiliary growth is seen in patients with a history of colorectal cancer.
