| 目的 观察肝脏原发性未分化多形性肉瘤（UPS）的CT与MRI表现。方法 回顾性分析8例经病理证实的肝脏原发性UPS患者的影像学资料。结果 6例肿瘤位于肝右叶，1例位于肝左叶，1例位于尾状叶。6例病灶呈不规则形，边界模糊；2例呈类圆形，边界尚清。7例呈混杂密度，1例密度较均匀。8例肿瘤增强扫描动脉期均呈轻度不均匀强化，静脉期肿瘤强化程度、范围均进一步增加；6例肿瘤延迟期持续强化。4例肿瘤并发下腔静脉或门静脉癌栓。结论 肝脏UPS的CT及MRI表现具有一定特征性，有助于诊断。 |

| Objective To investigate CT and MRI characteristics of liver primary undifferentiated pleomorphic sarcoma(UPS). Methods Data of 8 cases of pathologically confirmed liver UPS were analyzed retrospectively. Results The tumors located in right liver (n=6), left liver (n=1) or caudate lobe (n=1). Irregular shape and ill-defined boundary were found in 6 cases, while regular shape and well-defined boundary were found in the other 2 cases. The lesions in 7 cases showed heterogeneous density, and demonstrated homogeneous density in 1 case. Slight heterogeneous enhancement in arterial phase and progressive enhancement in portal phase were observed in all 8 cases, while continuous enhancement was observed in 6 cases. Tumor thrombi in inferior vena or portal vein were observed in 4 cases. Conclusion CT and MRI manifestations of primary liver UPS are characteristic in certain degree, therefore being helpful to the diagnosis of this disease. |
