Fig. 1From: Successful radical surgical resection of initially unresectable intrahepatic cholangiocarcinoma by downsizing chemotherapy with gemcitabine plus cisplatin: a case reportRadiological examinations before (a, b, and c) and after (d, e, and f) downsizing chemotherapy. a, b Computed tomography (CT) and magnetic resonance imaging (MRI) images of the liver showed focal dilation of the right intrahepatic bile duct and a 42-mm tumor in hepatic segments 1 to 8; the tumor was attached to the inferior vena cava (IVC) (a axial view of CT, b coronal view of MRI). c Positron emission tomography (PET) showed fluorodeoxyglucose (FDG) uptake in the para-aortic lymph nodes. d, e The size of tumor decreased to 18 mm, and the tumor was no longer attached to the IVC (d axial view of CT, e coronal view of MRI). f No FDG uptake was seen in the para-aortic lymph nodesBack to article page
