目的探讨肝血管平滑肌脂肪瘤(angiomyolipoma,AML)的超声造影表现.方法回顾性分析9例经病理确诊的肝AML患者共10个病灶的常规超声和超声造影表现.超声造影采用SonoVue和对比脉冲序列成像技术.结果常规超声7个病灶呈现混合回声,即明显高回声伴片状低回声;3个病灶呈明显高回声.彩色多普勒超声检查所有病灶均测得动脉血供,且血供丰富或较丰富或稀少,阻力指数平均0.53±0.10(0.48～0.62).超声造影显示9个病灶动脉期均呈高增强;门脉期5个为等增强,1个为高增强,3个为低增强;延迟期6个为等增强,3个为低增强.1个病灶三期均为低增强.结论超声造影上肝AML的增强表现具有一定特征性,可用于提示诊断,但仍需积累更多经验.

Objective To investigate the features of hepatic angiomyolipoma(AML) on contrast enhanced ultrasound (CEUS). Methods Ten pathologically proved AML lesions in 9 patients were evaluated by using baseline ultrasound and CEUS. CEUS was performed with contrast pulse sequencing technique and the contrast agent of SonoVue. Results On baseline ultrasound, 7 lesions exhibited mixed echoic,which was obvious hyperechoic combined with partly of hypoechoie; 3 lesions exhitited obvious hypereehoic. On color Doppler flow imaging artery signals were detected in all lesions. And the lesions had plenty or slightly plenty of artery supply,with resistive index about 0.53 4±0.10 (0.48~0.62). On CEUS, in the arterial phase, 9 lesions exhibited hyper-enhanced. In the portal phase, 5 lesions exhibited iso-enhancement,1 lesion was slightly hyper-enhancement and 3 lesions was hypo-enhancement. In the late phase 6 lesions were iso-enhancement and 3 lesions were hypo-enhancement. One lesion was all hypo-enhancement in all three phases. Conclusions There are some characteristic manifestations of hepatic AML in CEUS, which are helpful for the diagnosis of hepatic AML in a way,but we still need more experiences.
