| 目的 探讨婴儿型肝脏血管内皮细胞瘤（IHH）的CT表现特征。方法 回顾性分析16例经手术病理及临床诊断为IHH患儿的CT表现。结果 16例患儿中，单发病灶10例、多发病灶6例，均为肝内富血供病灶，动脉期呈明显环形强化，单发病变环形强化下方见向中心辐射的线状强化。多发病灶中4例环形强化中心区域见类圆形片状强化，静脉期及延迟期强化范围增大，1例多发病变强化类似于单发病灶强化方式，1例IHH Ⅱ型病灶小且多发，动脉期表现为边缘间断细线状强化，部分病灶线状强化下方见小结节状强化，静脉期结节强化范围增大，线状强化范围增大不明显。结论 IHH的CT表现具有一定特征性，其CT增强表现对本病的诊断更具意义。 |

| Objective To explore the CT features of infantile hepatic hemangioendothelioma (IHH). Methods CT imaging features of 16 IHH patients confirmed by surgical pathology and clinical diagnosis were retrospectively reviewed. Results Of 16 patients, there were single lesion in 10 cases and multiple lesions in 6 cases. All the lesions were rich in blood supply, and the arterial phase showed obviously rings enhanced. Some linear enhancement towards to the center below the annular enhancement of solitary lesions were found. There were patchy enhancement in annular enhancement center area, and the area of enhancement obvious increasing in venous phase and delayed phase in 4 cases with multiple lesions, enhancement mode was similar to single lesion in 1 case with multiple lesions. The lesions of IHH Ⅱ were small and multiple, and showed intermittent line shaped edge enhancement; some lesions below the linear enhancement showed small nodular enhancement and the area of nodular enhancement enlarged in venous phase, the range of linear enhancement was not obvious. Conclusion CT manifestations of IHH have some characteristics, and the enhancement of CT is more important in the diagnosis of this disease. |
