Radiological diagnosis and staging of hilar cholangiocarcinoma

Figure 10 Liver infiltration of cholangiocarcinoma. A: Coronal reconstructed multidetector computed tomography shows a periductal mass at the hepatic confluence consistent with cholangiocarcinoma (arrow); B: Axial computed tomography of the same patient shows a hypoenhancing mass involving the liver parenchyma and hilar vessels (arrow) consistent with tumoral infiltration by cholangiocarcinoma.
