Abstract:
Objective To analyze the computed tomography(CT)and magnetic resonance imaging (MRI)appearances of primary clear cell carcinoma of the liver (PCCCL)and evaluate the value in the diagnosis of the disease.Methods CT and MR images of 38 patients of pathologically confirmed PCCCL were evaluated retrospectively.Twenty-six patients underwent CT,23 underwent MRI, and 1 1 underwent both CT and MRI.Results In pre-contrast CT scanning,24 PCCCLs appeared hypodense and 2 hyperdense.As for MRI 1 9 of the 23 PCCCLs were hypointense and 4 were iso-hypointense on T1 WI.While on T2 WI,22 cases were heterogeneously hyperintense,and 1was iso-hypointense.On the arterial phase of CT/MRI,all cases presented intense enhancement,and on the portal venous phase,35 cases(35/38,92.1%)were relatively hypodense/hypointense and 3 were slightly hyperdense/hyperintense.Among the tumors larger than 3 cm(n=22),nodular enhancement pattern was found in 14 cases(63.6%,14/22).The capsular rim en-hancement was demonstrated in 26 cases.Conclusion PCCCL showed similar dynamic enhancement pattern as common hepatocellu-lar carcinoma,but also depicted specific imaging features.
