Case | Author, year | Age/sex | Radiologic findings | Surgical findings | Treatment |
|---|---|---|---|---|---|
1 | Shimura et al. [7] | 59/male | Irregular, incomplete stenosis from hilum to the lower part of the bile duct | Mass (4.5 × 3.5 cm) around the EHD | Right trisegmentectomy + caudate lobectomy |
2 | Shito et al. [9] | 71/male | Dilatation of IHD with a circumscribed heterogeneous mass in the main hepatic junction | Dense, white, nodular mass (5.0 × 2.5 cm) in the main hepatic junction | Left hemihepatectomy + caudate lobectomy + radical bile duct resection + Roux-en-Y hepaticojejunostomy + chemotherapy (CHOP, 3 cycles) |

[8] | 62/male | Dilatation of IHD with long, segmental, circumferential wall thickening of entire extrapancreatic portion of CBD + cystic duct + right posterior, anterior segmental IHD + left secondary biliary confluence | Diffuse wall thickening of EHD with smooth inner and outer surface without mass lesion | Right hemihepatectomy + caudate lobectomy + radical bile duct resection + Roux-en-Y hepaticojejunostomy + chemotherapy (CVP, 6 cycles) |
4 | MiKail et al. [10] | 58/female | Dilatation of IHD with a mass at liver hilus with intrahepatic biliary dilatation | 4 cycles of R-CHOP (rituximab/cyclophosphamide/doxorubicine/vincristine/prednisolone) | |
5 | This case | 86/female | Diffuse dilatation of IHD and wall thickening of CHD | Intraluminal mass in the proximal CBD and on the duodenal side, a spreading tumor-like lesion | Radical bile duct resection + Roux-en-Y hepaticojejunostomy |
