摘　　要：目的探讨肝脏血管平滑肌脂肪瘤(HAML)的超声声像图特点。方法回顾分析经手术组织病理学证实的9例HAML患者灰阶超声、多普勒超声及超声造影表现,并与病理结果进行对照研究。结果 9例HAML均为单发,男/女比=1/2;肿瘤最大直径28mm～115mm,平均74.9±30.5mm;表现为圆形或椭圆形,边界清晰。7个肿块主要为高回声,2个主要为低回声。超声报告仅1例诊断完全正确,4例仅作实性占位提示,2例误诊为肝癌,1例误诊为右肾上腺肿瘤,1例误诊为肝血管瘤;对7例肿块进行了多普勒彩超检查,显示肿块内部呈不同程度的血流信号,其中血流丰富2例。1例进行了超声造影检查,表现为动脉早期快速增强,门脉期与延迟期与肝实质呈等回声。结论 HAML的超声表现具有多样性,以高回声表现为主,多数CDFI及超声造影表现为富血供表现。Objective To analyze the uhrasonographic characteristics of hepatic angiomyolipoma （HAML）. Methods Nine patients with HAML were retrospectively reviewed,and the characteristics of gray-scale sonogram, Doppler ultrasound and contrast enhanced uhrasonography （CEUS）were conducted and the pathological histology features of the HAML were assessed simultaneously. Results All the nine patients had a single mass in the liv- ers and the ratio of male to female was 1：2;The HAMLs displayed a round or an elliptic well-defined mass;The mean largest diameter were 74.9±30.5mm with a range from 28 mm to 115 mm;On gray-scale sonogram,7 lesions （77.8%）exhibited hyperechoic and 2 lesions （22.2%）hypoechoic;Only one lesions were diagnosed as HAML cor- rectly before operation,while 4 lesions reported as space occupying lesions of the livers,two lesions were misdiag- nosed as liver cancer, 1 as hemangioma,and one as tumor of right adrenal gland;Seven lesions were checked with Doppler ultrasound,and there were blood flow sign in the lesions in various degree and 2 lesions were hypervas- cular;One lesion was examined with CEUS,and the lesion exhibited hyper-enhanced in the early arterial phase and iso-enhancedment in portal and late phase. Conclusions The appearances of HAML is diverse. Most HAMLs exhibits hyperechoic with hypervascularity in Doppler ultrasound and CEUS.
