摘　　要：目的:总结分析肝脏未分化胚胎性肉瘤MSCT表现,加深认识,提高本病术前影像诊断准确率。材料与方法:搜集7例经病理及免疫组织化学确诊的肝脏未分化胚胎性肉瘤临床及影像资料。结果:本组病例男4例,女3例,年龄5岁~69岁,既往无基础性肝病,临床表现无特异性,以腹胀、腹痛不适、发热等就诊,MSCT共性表现为肝右叶单发巨大低密度肿块,呈类圆形囊性或实性,其中实质性肿块5例,囊性肿块2例,密度不均,病灶边界清楚,大小在7cm^18cm之间。多期增强扫描实性成分呈持续轻中度不均匀强化,囊性成份无强化。结论:本病各年龄段均可发生,无明显性别差异,影像学表现为肝右叶巨大肿物,强化方式以延迟持续强化为主,影像、临床均无特征表现,术前确诊困难。患者肝功能正常,AFP、血清肿瘤标记物检查阴性。Purpose： To summarize and analyze the MSCT features of undifferentiated sarcoma of the liver,deepen the understanding and improve the diagnostic accuracy of the disease. Materials and Methods： The clinical and imaging data of 7 cases of undifferentiated sarcoma of the liver,which were confirmed by pathology and immunohistochemistry,were collected. Results： There were 4 male and 3 female patients,aged 5 to 69 years old,with no basic liver disease,clinical manifestations of non specificity,abdominal distension,abdominal pain,fever and other medical treatment,MSCT common features of liver right lobe single huge low density mass,5 cases of solid mass,2 cases of cystic masses,density is not clear,the size of the lesions in 7cm - 18 cm. The solid component of the multi phase enhancement scanning is in a continuous light and moderate enhancement and no enhancement in the cystic components. Conclusion： There were no significant gender differences in the age of the disease,and the imaging features of the patients with massive liver lobe were characterized by a delayed continuous enhancement. Patients with normal liver function,AFP,serum tumor markers test negative.
