摘要
目的:探讨动态增强CT在鉴别诊断肝脏血管肉瘤和血管瘤中的价值。方法:对4例临床病理证实的肝血管肉瘤(21个)和12例临床明确诊断的肝血管瘤(30个)的CT资料进行回顾性分析,所有患者均行CT平扫及三期增强扫描。结果:51个病灶在增强扫描早期阶段表现为多种强化模式。两种肿瘤的影像学特征中增强早期阶段的强化方式(非周边性强化)和合并动静脉短路这2个特征在两组间的差异有统计学意义(P<0.05),而延迟期强化的特点在两种肿瘤间的差异无统计学意义(P>0.05)。结论:增强扫描早期瘤结节内非周边性强化和合并动静脉短路的特点是鉴别肝血管肉瘤和血管瘤的重要指标,尤其是在鉴别迟期强化的肝血管肉瘤和血管瘤中有重要意义。
Objective：To investigate the diagnostic value of dynamic contrast enhanced CT in differentiating hepatic angiosarcomas from hemangiomas. Methods：The CT features of 51 hepatic lesions including 21 angiosarcomas in 4 cases and 30 hmeangiomas in 12 cases confirmed by pathology or clinical follow-up were retrospectively analyzed. All patients under- went pre-contrast and three phases contrast enhanced CT scan （CECT）. Results：In early phase of CECT,the 51 hepatic le- sions showed variable patterns. The features of non-peripheral enhancement in early phase of CECT （P^0.05） and associ- ated with arterioportal shunting in hepatic angiosarcomas were significantly different from those in cavernous hemangiomas, whereas there was no significant difference in feature of delayed enhancement between the liver angiosarcomas and hemangi- omas （P〉0.05）. Conclusion：Contrast enhanced patterns in early phase and associated with arterioportal shunting are im- portant signs in differentiating hepatic angiosarcomas from hemangiomas, especially in the tumors presenting delayed en- hancement.
