Ewing's sarcoma (ES) is a tumor that often occurs in the long bones and rarely arises from visceral organs primarily. Here, we report a case of primary hepatic ES, discuss its computed tomography (CT) and gadobenate dimeglumine-enhanced magnetic resonance (MRI) features. This is the first Chinese and fifth primary hepatic ES case reported, based on a literature review. Imaging examinations showed that the tumor was solid, with necrosis and hemorrhage. Contrast-enhanced images showed that the tumor was hypervascular and especially had heterogeneous signal intensity on hepatobiliary phase MRI images. Intratumoral vessels and vascular invasion were also present.
尤因肉瘤（ES）是一种常发生于长骨且很少主要起源于内脏器官的肿瘤。在此，我们报告一例原发性肝脏ES病例，并讨论其计算机断层扫描（CT）和钆贝葡胺增强磁共振成像（MRI）特征。基于文献综述，这是首例中文报道的原发性肝脏ES病例，也是第五例原发性肝脏ES病例。影像学检查显示肿瘤为实性，伴有坏死和出血。增强图像显示肿瘤血供丰富，尤其是在肝胆期MRI图像上信号强度不均匀。肿瘤内血管及血管侵犯也存在。
