| 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15~106 mm，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。 |

| Objective To explore the application of MSCT enhanced scanning in infantile hepatic hemangioendothelioma. Methods Totally 9 cases of infantile hepatic hemangioendothelioma were examined by MSCT. The CT characteristics of the tumor, including morphology and distribution, size, density, edge, enhancing type and hepatic artery-vein shunting, were retrospectively analyzed. Results The shape of tumors were round or quasi-round. Five cases were single lesions, and isolated in a single liver lobe. The maximum long diameter were 15-106 mm, mean (51.40±31.53)mm. Four cases were multiple lesions and the lesions were diffusely distributed in the left and right lobes. The maximum long diameter were 12-99 mm, mean (45.75±32.89)mm. In plain scanning, 2 cases showed equal density and 7 cases showed low density. The CT value were 25-46 HU, mean (37.78±22.17)HU. The stripped or punctuate calcifications were shown in 2 cases. The edge of single lesions were not clear, while the edge of multiple lesions were clear. In arterial phase of enhanced scanning, a petal like and nodular enhancement were found at the edge of the lesion in 7 cases, and strip shaped and nodular shaped enhancement at the centre of the lesions. The CT value was 139-263 HU, mean (188.89±98.42)HU, which was the same as aortic density. Complete enhancement was found in another 2 cases. In portal vein phase, the contrast media was filled from edge to the center gradually. In the delayed phase, besides 2 cases were with incomplete filling, all the 7 cases were filled completely, showing isodensity or slightly high density. In arterial phase, the portal vein showed early development simultaneously in 7 cases, hepatic vein showed early development simultaneously in 2 cases. The connection of hepatic vein and the lesions looked like a "lollipop" in the vascular VR. Conclusion The complete filling in the delayed phase is the characteristic sign of infantile hepatic hemangioendothelioma. The application value of enhanced scanning is significant to find the complications of hepatic artery-potal vein shunting (HA-PVS) and hepatic artery-hepatic vein shunting (HA-HVS). |
