B型超声对肝血管瘤的再认识

Recognition Again:Liver Angioma by B-type Ultrasound

目的本文对１１０例肝血管瘤病例进行总结。方法Ｂ型超声。结果发现７０％以上的病人瘤体位于肝右叶，瘤体以１～２ｃｍ居多，８０％以上呈强回声，在１１例低回声瘤体中仅６例有强回声边缘。核素肝血池的阳性率与瘤体大小有明确关系，对直径大于３ｃｍ的血管瘤阳性率可达１００％。此组病例中有１例由强回声转变为低回声，另１例由低回声转变为强回声。结论大多数肝血管瘤呈强回声。

Objective One hundred eleven liver angioma cases were summarized.Methods B-type ultasound was used for detecting angina.Results More than 70 per cent angiomal localized in the right lobe of live.Most of them were 1～2cm in diameter,and 80 per cent angioma were hyperechoic.Six out of 11 hypoechoic angioma had enhanced margin. The diagnosis rate of angioma by radionuclide imaging,related to the diameter,was 100 per cent when angioma was larger than 3cm.More over,we found that one case had the sonographic feature from hyper-to hypo-echoic,but an other had opposite featuren.Conclusion Most of liver angioma were hyperechoic,and the sonographic feature of angioma was changeable.
