ABSTRACT
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.
