Because of the slow flow in the venous spaces of large-vessel hemangiomas, demonstration of color flow signals with conventional color Doppler or power Doppler sonography may be difficult. We report the case of a 22-year-old female patient with a soft tissue tumor containing multiple fluid-filled spaces in the right supraclavicular region. Gray-scale, color, and power Doppler sonography could not differentiate between cystic lymphangioma and large-vessel hemangioma. The intravenous echo-enhancing contrast agent Levovist was administered, and a significant echo-enhancing effect on color and power Doppler imaging was demonstrated in the fluid-filled spaces and lasted for about 3 minutes. Histopathologic study of the excised tumor confirmed the sonographic diagnosis of hemangioma. Levovist appears useful in depicting slow flow in a large-vessel hemangioma.
由于大血管性血管瘤静脉腔内血流缓慢，使用传统彩色多普勒或能量多普勒超声检查显示血流信号可能会有困难。我们报告一例22岁女性患者，其右锁骨上区有一软组织肿瘤，内含多个液性腔隙。灰阶、彩色及能量多普勒超声无法鉴别囊性淋巴管瘤和大血管性血管瘤。静脉注射超声造影剂声诺维后，液性腔隙在彩色及能量多普勒成像上显示出显著的增强回声效应，且持续约3分钟。对切除肿瘤的组织病理学研究证实了超声诊断的血管瘤。声诺维似乎有助于显示大血管性血管瘤内的缓慢血流。
