Abstract:
Objective To investigate the MRI features of combined hepatocellular-cholangiocarcinoma(cHCC-CC).Methods The MR imaging features of 8 patients with cHCC-CC confirmed by histopathology were analyzed retrospectively.And 3 patients among them performed MR dynamic contrast scanning with gadoxetic acid(Gd-EOB-DTPA)-a hepatocyte-specific MRI contrast agent.Results MRI showed hypointensity on T1 WI and hyperintensity on T2 WI of tumor's solid components.Dynamic MRI enhancement demonstrated peripheral hyperenhancement of the lesion (n =7) and global hyperenhancement(n=1) in arterial phase,progressively delayed or continued enhancement of the central area in portal venous phase and equilibrium phase,meanwhile the peripheral hyperenhancement of the lesion in arterial phase washed out(n=6),edge enhancement continued(n=1),and enhancing area extended progressively(n=1) which the peripheral hyperenhancement in arterial phase remained.Enhancing pseudocapsule were observed in equilibrium phase(n=6).3 patients injected with Gd-EOB-DTPA presented a target-like appearance in hepatobiliary phase,defined as a peripheral hypointense rim compared to the central area with delayed enhancement of the lesion.Conclusion Dynamic MRI can be a certain value in the preoperative dagnosis of cHCC CC.
