【摘要】Objective To summarize the computed tomography (CT) features of infantile hepatic hemangioendotheliomas (IHH), analyze the difference of CT expression in different diameters of tumors, and to understand the influence of tumor diameter on CT.Methods The CT findings of twenty two IHH cases proved pathologically were retrospectively analyzed. The distribution, number, size, imaging appearance and enhancement pattern of the tumors were evaluated, to analyze the difference of CT expression in tumors with different diameters.ResultsA total of 306 IHH lesions were detected on CT in 22 cases. CT scan showed 302 lesions (98.7%) were uniformly low density, calcification and hemorrhage were seen in the 4 lesions (1.3%). In CT enhanced arterial phase, 158 lesions (51.6%) showed ring enhancement edge, 148 lesions (48.4%) showed homogeneous enhancement around the tumor, 102 lesions (33.3%) showed fibrous cord like enhancement, 88 lesions (28.8%) showed nodular enhancement. In arterial phase, the tumor diameter <1.0 cm, all lesions showed homogeneous enhancement; lesions showed mixed enhancement pattern when tumor diameter was 1.0-2.0 cm; lesions showed with the edge ring
enhancement for 98.2% (108/110) when tumor diameter was >2.0 cm. In the portal vein stage, all the lesions showed enhancement. In the delayed period, most lesions showed whole tumor enhancement (284/306, 92.8%), with statistically significant differences between the groups (χ2=330.56,P<0.001).Conclusion The CT expression of IHH has some characteristics, and the diameter of the tumor has some influence on the performance of CT.%目的 总结婴儿型肝脏血管内皮细胞瘤(IHH)的CT表现,分析不同直径的肿瘤在CT表现上的差异,了解肿瘤直径对CT表现的影响.方法 回顾性分析2010年3月至2016年5月开平市中心医院和中山大学附属第一医院22例经病理证实的IHH的CT表现,评估内容包括肿瘤的分布、数量、大小和CT增强的模式,分析不同直径的肿瘤在CT表现上的差异.结果 22例IHH中共发现病灶306个.CT平扫显示302个(98.7%)病灶为均匀低密度,4个(1.3%)病灶内见钙化或出血.CT增强扫描动脉期,158个(51.6%)病灶表现为边缘环形强化,148个(48.4%)呈全瘤均匀强化,102个(33.3%)表现为纤维条索样强化,88个(28.8%)呈结节样强化.当肿瘤直径<1.0 cm,动脉期全部病灶均表现为全瘤均匀强化;肿瘤直径在1.0~2.0 cm时,增强扫描动脉期病灶表现为混合性强化模式;肿瘤直径>2.0 cm时,增强扫描动脉期以边缘环形强化为主(108/110,98.2%).门静脉期所有的病灶均表现为强化范围扩大;延迟期大多数病灶表现为全瘤均匀强化(284/306,92.8%),各组间的差异存在统计学意义(χ2=330.56,P<0.001).结论 IHH的CT表现有一定的特征性,肿瘤的直径对CT表现有一定的影响. 【总页数】5页(260-264)
