Tumeurs de Klatskin : ce qui est important à connaître

Klatskin tumors are rare and have poor prognosis. The only curative treatment is surgical resection. Unfortunately, two-thirds of tumors are not resectable at diagnosis. The imaging appearance is variable and depends on morphological type. The main purpose of imaging is to establish a precise staging that will guide the type of surgical resection and avoid unnecessary surgery. For this, the radiologist should know the criteria for non-resectability and the principles of curative surgery. This will enable a report useful for a suitable therapeutic approach.
