Hilar cholangiocarcinoma: Cross sectional evaluation of disease spectrum.

Mahajan MS, Moorthy S, Karumathil SP, Rajeshkannan R, Pothera R - Indian J Radiol Imaging (2015 Apr-Jun)

Bottom Line: Although hilar cholangiocarcinoma is relatively rare, it can be diagnosed on imaging by identifying its typical pattern.In most cases, the tumor appears to be centered on the right or left hepatic duct with involvement of the ipsilateral portal vein, atrophy of hepatic lobe on that side, and invasion of adjacent liver parenchyma.Multi-detector computed tomography (MDCT) and magnetic resonance cholangiopancreatography (MRCP) are commonly used imaging modalities to assess the longitudinal and horizontal spread of tumor.

Type IIIb moderately differentiated mass-forming hilar cholangiocarcinoma. (A) Contrast-enhanced coronal CT image shows tumor mass in common hepatic duct (black single arrow) extending to the left hepatic duct (black double arrow). (B-D) Axial T2W images with and without fat suppression and coronal T2W image very well show mass-forming tumor in dilated left biliary radicles (white single arrow). (E) MRCP image show isolation of left sectoral ducts (white single arrow)

Figure 7: Type IIIb moderately differentiated mass-forming hilar cholangiocarcinoma. (A) Contrast-enhanced coronal CT image shows tumor mass in common hepatic duct (black single arrow) extending to the left hepatic duct (black double arrow). (B-D) Axial T2W images with and without fat suppression and coronal T2W image very well show mass-forming tumor in dilated left biliary radicles (white single arrow). (E) MRCP image show isolation of left sectoral ducts (white single arrow)

Mentions: The tumor forms a small nodule of usually 1-2 cm in diameter with bile duct dilatation. It obstructs the bile duct lumen in early stage and causes obstructive jaundice, infiltrates the wall, and eventually invades the periductal tissue. The surface of the lumen is usually irregular. Because the size of the tumor is small, images should be very carefully assessed [Figures 6 and 7].[9]
