title: CT and MRI findings of sarcomatoid cholangiocarcinoma.
abstract: Computed tomography (CT) and magnetic resonance imaging (MRI) findings for a case of intrahepatic sarcomatoid cholangiocarcinoma is presented. A 48-year-old man with upper abdominal pain underwent contrast-enhanced CT and MRI. A 13 × 10 × 7 cm mass was seen in the left liver lobe, which had hypodense internal architecture on CT and mixed signal intensities on both T1- and T2-weighted images with an overwhelmingly hypointense signal on T1-weighted images and a hyperintense signal on T2-weighted images. The lesion had heterogeneous enhancement on both CT and MRI. A satellite nodule with the same imaging features was distinctive for the lesion.
