目的：探讨原发性肝血管肉瘤（ HAS）的MRI表现。方法回顾性分析第二军医大学东方肝胆医院2009至2011年经手术病理证实的3例HAS患者的临床、病理和术前MRI表现。结果3例HAS患者包括男性1例和女性2例，年龄35～71岁。所有病灶在MRI的T1WI和T2WI均表现为混合信号强度。所有病灶均存在肿瘤内出血、坏死。 GD-DTPA增强扫描后动脉期病灶均为不均匀轻度强化，延迟期病灶表现为持续渐进增强而瘤中心无强化。结论当肝内肿瘤MRI表现为坏死、出血，增强后延迟期病灶渐进强化应考虑到HAS的可能。

Objective To investigate the MRI findings of primary hepatic angiosarcoma ( HAS). Methods Three cases of HAS confirmed by pathologically were retrospectively analyzed between 2009 and 2011 in Shanghai Eastern Hepatobiliary Surgery Hospital of the Second Military Medical University . Results OnMRI, all cases (two females and one male, age from 35 years to 71 years) appeared as hypo mixed hyper signal-intensity both in axial T1WI and T2WI.All lesions had intratumoral hemorrhage and necrosis. After GD-DTPA injected on arterial phase , three cases demonstrated heterogeneously mild enhanced and continued progressive enhancement on delay phase without enhancement of tumor center . Conclusion When the MRI representations of intrahepatic tumor show intratumoral hemorrhage and necrosis and continued progressive enhancement on delayed phase , HAS should be considered .
