Perihilar CCA arising from the cystic duct and proximal gall bladder (arrows) with invasion of common hepatic duct. The pCCA is mildly hyperintense on T2-weighted image (a), hypointense on T1-weighted image (b) and shows post contrast enhancement (c). Both MRCP (d) and ERCP (e) demonstrate the stricture of the common hepatic duct till the confluence above and cystic duct insertion below. The gall bladder is not visualized on ERCP and the irregularity of the proximal cystic duct (arrowhead) is due to the tumor.
