CT and MRI findings of primary hepatic giant cell tumor of soft tissue: A case report

Abstract

AbstractPrimary giant cell tumor of soft tissue (GCT-ST) is a low-grade malignant tumor and uncommon cancer originating from soft tissue. Primary hepatic GCT is an extremely rare finding. Only a handful of cases have been reported in the literature. Although GCT-ST has a relatively low malignant potential tumor in the view of histology, some patients who suffered from this tumor have poor prognosis after surgery because of the aggressiveness. Thus, the early diagnosis is important, and a preoperative imaging can supply the evidence of differential diagnosis to evaluate tumor malignancy. In this study, we systematically present a rare case of 56-year-old women with chills, fever, jaundice and anorexia for 3 days. CT showed a huge and multinodular confluent lesion in the left lobe of the liver, and it had a calcification component. This tumor is characterized by fibrous components and calcification, which showed iso-intense with peripheral hypo-intense on T1WI, and mainly inhomogeneous hypo-intense on fat-suppressed T2WI. Moreover, it was mainly hypointense and peripheral linear hyperintense on DWI images with a b-value of 800 (b800) and iso-hyperintense on ADC.
