目的探讨婴儿型肝脏血管内皮细胞瘤(IHHE)的超声表现及其诊断价值。方法回顾性分析经CT、MRI和/或病理结果证实的22例IHHE患儿的超声表现。结果超声显示8例单发型病灶边界清,回声不均匀,其中6例内见钙化灶;10例多发型病灶均为低回声,边界呈高回声;4例弥漫型中3例为低回声,肝脏回声紊乱。彩色多普勒显示21例瘤内血供丰富,部分瘤内及周边可见血管扩张,5例存在动静脉瘘。随访中3例完全消退,3例未见明显变化,余14例病灶均有不同程度缩小,血流信号减少,部分病灶内钙化增多。结论 IHHE好发于6个月内婴儿,大多数可自行消退,预后良好。其超声表现具有一定的特征性,有助于本病的诊断和随访。
Objective To investigate the ultrasonographic features and diagnostic value of IHHE in infants. Methods The ultrasound findings of 22 IHHE children confirmed by CT, MRI and / or pathology were retrospectively analyzed. Results Ultrasonography showed that 8 cases of single-type lesions had clear boundary and uneven echoes, of which 6 cases had calcification, 10 cases of multiple lesions were hypoechoic and the border was hyperechoic, and 3 of 4 cases were diffuse hypoechoic and liver Echogenic disorder. Color Doppler showed 21 cases of tumor blood supply is rich, some of the tumor can be seen around the blood vessels and peripheral expansion, arteriovenous fistula in 5 cases. 3 cases completely disappeared during follow-up, 3 cases showed no significant change, more than 14 cases of lesions were reduced to varying degrees, reduced blood flow signal, increased calcification in some lesions. Conclusion IHHE occurs in infants within 6 months, most of them can be spontaneous regression, the prognosis is good. Its ultrasound performance has a certain characteristic, contribute to the diagnosis and follow-up of the disease.
