头部右转时反复间歇性眩晕1年余,站位、坐位或平躺时皆发作,发作时都与头部向右旋转有关。

58岁,男性。

头部右转时反复间歇性眩晕1年余,站位、坐位或平躺时皆发作,发作时都与头部向右旋转有关。

头颈CTA显示,C5-C6接近右侧椎动脉处可见骨赘(图1,箭头):

颈部椎动脉动态超声显示,头右转时收缩期峰值流速从50cm/s增加到159cm/s(图2A和2B)。向左转头没有发现异常(图2C)。颅内椎动脉动态TCD显示向右转头时收缩期峰值流速从24cm/s降低到15cm/s(图2D):

DSA显示头位处于标准位置时右侧椎动脉未见异常,但将头部转向右侧会引起右侧椎动脉局部狭窄(图3A和3B)。左椎动脉先天性发育不良(图3C)。此外,还可见基底动脉中部慢性闭塞,双侧大脑后动脉、双侧小脑上动脉和基底动脉尖由前循环通过右后交通动脉供血(图3D和3E):

最终诊断为Bow Hunter’s综合征。
