目的探讨原发性肉瘤样肝细胞癌的CT表现。资料与方法回顾性分析7例经手术病理证实的原发性肉瘤样肝细胞癌的CT表现。7例均行CT平扫和动态增强扫描。结果 7例病灶平扫均为低密度,其中6例病灶内见不规则更低密度影。增强扫描动脉期所有病灶均有强化表现,门静脉期显示原动脉期强化区域密度减低,延迟期4例病灶边缘及内部实性区有轻度延迟强化。7例中,单发6例,多发1例。结论原发性肉瘤样肝细胞癌具有肝细胞癌和肉瘤的双重特征,CT有助于提高该病的诊断准确性。
Objective To investigate the CT findings of primary sarcomatoid hepatocellular carcinoma. Materials and Methods Retrospective analysis of CT findings of 7 cases of primary sarcomatoid hepatocellular carcinoma confirmed by surgery and pathology. Seven cases underwent CT scan and dynamic contrast-enhanced scan. Results The lesions of 7 cases were all low density, of which 6 cases showed irregular lower density. All the lesions in the enhanced arterial phase showed enhanced performance. The portal venous phase showed a decrease in density in the enhancement phase of the primitive arterial phase. There were mild delayed enhancement in the edge and internal solid area of the delayed phase in 4 patients. Of the 7 cases, 6 were single and 1 was multiple. Conclusion Primary sarcomatoid hepatocellular carcinoma has the dual characteristics of hepatocellular carcinoma and sarcoma. CT can help improve the diagnostic accuracy of the disease.
