目的 探讨肝腺瘤的超声表现特点.方法 分析10例肝腺瘤的彩色多普勒与超声造影表现.结果 彩色多普勒超声于所有病灶内均见丰富血流信号,呈"彩球征",瘤周测及条状大支血流.4例行超声造影,动脉相呈均匀快速高增强,早期见包膜下粗大滋养动脉分支显影;1例门脉相星轻度低增强,延迟相呈等增强;余3例门脉相呈等增强,延迟相呈轻度高增强,表现为"快进慢出"改变.超声造影4例肿瘤包膜均呈局部持续高增强.结论 肝腺瘤内丰富的血流信号,超声造影动脉相均匀快速高增强及早期包膜下粗大滋养动脉分支显影、包膜局部持续高增强等声像表现均具有一定的特征性.
目的 探討肝腺瘤的超聲錶現特點.方法 分析10例肝腺瘤的綵色多普勒與超聲造影錶現.結果 綵色多普勒超聲于所有病竈內均見豐富血流信號,呈"綵毬徵",瘤週測及條狀大支血流.4例行超聲造影,動脈相呈均勻快速高增彊,早期見包膜下粗大滋養動脈分支顯影;1例門脈相星輕度低增彊,延遲相呈等增彊;餘3例門脈相呈等增彊,延遲相呈輕度高增彊,錶現為"快進慢齣"改變.超聲造影4例腫瘤包膜均呈跼部持續高增彊.結論 肝腺瘤內豐富的血流信號,超聲造影動脈相均勻快速高增彊及早期包膜下粗大滋養動脈分支顯影、包膜跼部持續高增彊等聲像錶現均具有一定的特徵性.

Objective To probe the characteristic ultrasonic appearances of hepatic adenoma.Methods The appearances of color Doppler flow imaging(CDFI)and contrast-enhanced ultrasound(CEUS)in 10 cases of hepatic adenoma were analyzed.Results Rich blood flow signals were found in all the hepatic adenoma lesions on CDFI.Large blood flow signals were detected in the periphery of all tumors.On CEUS,peritumoral feeding vessels displayed in early arterial phase and homogeneous enhancement in arterial phase was observed in all the 4 cases.The tumor capsule was enhanced continuously in all cases.One case with isoechoic enhancement in delayed phase was found the contrast agent wash out in portal phase.The other 3 cases showed the‘fast-in and slow-out'appearance.which was iso-echoic enhancement in portal phase and slightly hyperechoic enhancement in delayed phase.Conclusions The rich blood flow signals,early displaying of peritumoral feeding vessels,homogeneous enhancement in the arterial phase and continuously enhanced tumor capsule on CEUS are the distinctive appearances of hepatic adenoma.
