Contribution of Bili MRI in the diagnosis of extrahepatic cholangiocarcinoma

Extrahepatic cholangiocarcinomas are malignant tumours that include hilar tumours, known as Klatskin tumours, and tumours arising in the middle and lower two-thirds of the main bile duct (MBD), known as distal cholangiocarcinomas.

The diagnosis of cholangiocarcinoma represents a real challenge, given the difficulty of accessing a cytological diagnosis. A non-contributory cytology may lead to the consideration of certain examinations, particularly MRI, for diagnostic purposes. We report here our experience in a series of 27 patients, followed for extrahepatic cholangiocarcinoma, reviewing the data in the literature.
