CCA of common hepatic duct with involvement of confluence. Ultrasound with color flow overlay (a) showing an echogenic mass (arrow) filling the common hepatic duct with upstream dilatation of the intrahepatic ducts. EUS image (b) showing a hilar lymph node and was sampled positive for carcinoma. Contrast enhanced CT in arterial phase (c) and portal venous phase (d) showing enhancing mass (arrow) within the duct and no major vascular involvement. The ductal mass is hyperintense on T2-weighted image (e) and hypointense on T1-weighted image (f) and shows concentric post contrast enhancement (g). MRCP (h) shows the confluence invasion and non- visualization of the common hepatic duct.
