【摘要】：目的探讨MSCT增强扫描在婴儿肝脏血管内皮细胞瘤中的应用价值。方法回顾性分析9例婴儿肝脏血管内皮细胞瘤的CT表现,包括形态与分布、病灶大小、密度、病灶边缘、强化特点及有无动脉静脉瘘。结果肿块呈圆形或类圆形,单发5例,局限于单侧肝叶,最大径15~106mm,平均(51.40±31.53)mm;多发4例,弥漫分布于肝左、右叶,最大径12~99 mm,平均(45.75±32.89)mm;2例平扫呈等密度,7例呈低密度;CT值25~46 HU,平均(37.78±22.17)HU,2例肿块内有条状、点状钙化。单发病灶边缘欠清楚,多发病灶边缘清晰。增强扫描动脉期7例病灶边缘呈花瓣状、结节状明显强化,内部呈条状、结节状强化,CT值139~263 HU,平均(188.89±98.42)HU,与主动脉密度相似;2例完全强化。门静脉期对比剂逐渐向中心填充。平衡期除2例不完全填充外,7例完全填充,呈等密度或稍高密度。7例动脉期门静脉同时显影,2例肝静脉与肝动脉同期显影;血管VR见肝静脉与病变连接呈"棒棒糖"样。结论平衡期肿瘤完全充填对比剂是婴儿血管内皮细胞瘤特征性强化表现,增强CT对发现其并发症肝动脉-肝静脉瘘、肝动脉-门静脉瘘有重要意义。
[Abstract]:Objective to evaluate the value of MSCT enhanced scanning in the diagnosis of hepatic angioendothelioma in infants. Methods CT findings of 9 cases of infantile hepatic hemangioendothelioma were retrospectively analyzed, including morphology and distribution, size, density and edge of the lesion. Results the tumor was round or round in 5 cases, limited to the unilateral lobe with a maximum diameter of 151.40 卤31.53 mm, multiple in 4 cases, distributed in the left and right lobes of the liver. The maximum diameter was 125.75 卤32.89 mm, with a mean of 45.75 卤32.89 mm in 2 cases. The CT value was 2546 HUU in 7 cases of plain scan, and the mean value was 37.78 卤22.17 HUU in 2 cases with calcification and calcification. The margin of single lesion was not clear. The edge of multiple lesions was clear. In arterial phase, 7 cases showed petal, nodular enhancement and stripe inside. The CT value of nodular enhancement was 139 ~ 263 HUU, with an average of 188.89 卤98.42 HUU. The density of the aorta was similar to that of the aorta in 2 cases with complete enhancement. Portal vein phase contrast agent was gradually filled into the center. In the equilibrium phase, 7 cases were completely filled except 2 cases without complete filling. The portal vein showed isodensity or slightly high density in 7 cases, and hepatic vein was developed simultaneously with hepatic artery in 2 cases. Conclusion the complete tumor filling contrast agent in balanced phase is the characteristic enhancement of angioendothelioma in infants, and contrast-enhanced CT is useful in detecting hepatic arterial-hepatic vein fistula. Hepatic arteriovenous fistula is of great significance.
