We report four patients with paralysis of downward gaze but with intact upward gaze, including one with detailed clinico-pathological studies and another with a focal computerized axial tomographic (CT) scan abnormality confirming the presence of bilateral lesions of the dorsomedial red nucleus, including the fasciculus retroflexus. It is suggested that sudden, permanent selective failure of downward gaze accompanied by transient disturbance of consciousness is an embolic syndrome of the posterior thalamosubthalamic or rubral artery.
我们报告了4例向下凝视麻痹但向上凝视正常的患者，其中1例进行了详细的临床病理研究，另1例经局部计算机断层扫描（CT）异常证实存在双侧背内侧红核病变，包括后屈束。提示突然发生的、永久性的选择性向下凝视障碍并伴有短暂意识障碍是丘脑底后动脉或红核动脉的栓塞综合征。
