Peripheral cholangiocarcinoma after preoperative chemotherapy. (a) Axial multi-slice CT image shows a small residual mass in the left lobe with thrombosis of the left hepatic vein. (b) The sagittal MPR of the 3D data set demonstrates much better the residual tumor cuff around the thrombosed left hepatic vein, which abuts the inferior vena cava. At surgery, the tumor could be resected along the IVC.
