10例肝脏小血管瘤的B超表现

THE B-MODEL ULTRASONOGRAPHIC'APPEARANCE OF SMALL HEPATIC HEMANGIOMAS ANALYSES OF TEN CASES

采用实时灰階B超发现10例肝脏小血管瘤病人(男性6例,女性4例)。年龄在30～64岁,其中4例经CT检查,2例经外科手术,1例经肝动脉造影检查证实为本病。全部病例经长期B超随访(最短的3年,最长的6年),B超所见肝内瘤体结节共16个,分布于肝右叶的有9例,于左叶的有1例。病灶最小的约1.0×1.7cm^2,最大的约3.0×5.0cm^2。强回声结节的9例,低回声结节的有1例。B超图象特点为肝内孤立性或多发性强回声结节,内部结构疏松呈小蜂窝状,边缘清晰、锐利,呈锯齿状或花边状。病灶对周围肝组织和肝内血管无挤压征象。长期B超随访观察,病灶大小无明显变化。

Ten cases of small hepatic hemangiomas were found by realtime ultrasonography (six male, four female, range from 30 to 64 years). Four cases were confirmed by Computed Tomographic examination, two cases by surgical operation and one case by hepatic angiography, The long-term follow-up was performed in all patients (three to six years). In ultrasonographic images the hepatic hemangiomas appeared primarily as nodular structure, hyperechoic in nine cases and hypoechoic in one case, which was located in the right lobe of liver in nine cases and in the left lobe of liver in one case. The smallest one was about 1.0×1.7cm^2 and the biggest one was about 3.0×5.0cm^2. The ultrasonographic appearance was characterized by hyperechoic, meshed, clearly and sharp marginated nodule. There was no pressure sign between lesions with surrounding hepatic tissue and intrahepatie vessels. The size of the lesions did not changed obviously after a long-term follow-up.
