Two cases of hepatic angiomyolipoma were studied by contrast-enhanced harmonic sonography. The special tumor hemodynamics, namely the efferent blood flow of the hepatic angiomyolipoma draining into the hepatic vein, were clearly shown on harmonic imaging, and they corresponded well with those seen on angiography and computed tomography during angiography. Benign hepatic tumors were diagnosed preoperatively in both cases according to the hemodynamic findings. Hepatic angiomyolipoma was finally identified histologically. The special tumor hemodynamics might be one of the important characteristics of hepatic angiomyolipoma. Contrast-enhanced harmonic sonography is useful for the detection of special tumor hemodynamics and may facilitate the differential diagnosis from other hepatic tumors, especially malignant liver tumors.
采用对比增强谐波超声检查对2例肝血管平滑肌脂肪瘤进行了研究。在谐波成像上清晰显示了肝血管平滑肌脂肪瘤特殊的肿瘤血流动力学，即其流出血流汇入肝静脉，这与血管造影及计算机断层扫描血管造影所见相符。根据血流动力学表现，两例均在术前诊断为肝脏良性肿瘤。最终经组织学检查确诊为肝血管平滑肌脂肪瘤。这种特殊的肿瘤血流动力学可能是肝血管平滑肌脂肪瘤的重要特征之一。对比增强谐波超声有助于检测特殊的肿瘤血流动力学，可能有助于与其他肝脏肿瘤尤其是肝脏恶性肿瘤进行鉴别诊断。
