| Abstract: | Background: Because of its poor prognosis, the diagnosis of hepatocellular carcinoma with sarcomatous change (HCCSC) is clinically important.
The purpose of this study is to elucidate the characteristic CT findings of HCCSC.
Methods: Two-phased dynamic incremental CT images of six histologically proven HCCSC were retrospectively reviewed.
Results: All tumors (100%) exhibited peripheral enhancement on delayed CT images. Lymphadenopathy was observed in 100% (six of six
patients); intrahepatic metastases, in 83% (five of six). Both metastatic lesions showed findings similar to those of the
primary hepatic tumors, such as peripheral enhancement. Histopathologically, delayed and/or prolonged peripherally enhanced
areas consisted of viable cancer cells with sarcomatous changes.
Conclusions: The appearance of HCCSC on CT is that of an irregularly demarcated intrahepatic mass with delayed or prolonged peripheral
enhancement, frequently with intrahepatic metastases and lymphadenopathy.
