Peripheral cholangiocarcinoma with involvement of confluence. Infiltrating pCCA of the left hepatic duct (arrow) isodense to liver parenchyma on axial contrast enhanced CT (a) with dilation of the left hepatic ducts. The ductal thickening is hyperintense (arrow) on T2-weighted MRI image (b) with extension to the confluence causing mild dilatation of the right hepatic ducts demonstrated better on MRCP (c).
