The case of a 55-year-old female is presented, in whom first a loss of the vestibular and hearing function on the left side occurred with sudden onset, and 3 days later an additional loss of functions on the right side occurred. No other neurological symptoms were present. Angiography and MRI scan revealed vertebrobasilar dolichoectasia with a thrombus attached to the wall of the basilar artery. Anticoagulative therapy improved hearing function on the right side sufficiently to allow conversation. Vestibular organs remained unresponsive to caloric irrigation. This bilateral loss of eighth nerve function is discussed as a rare case of bilateral ischemia of the labyrinthine artery due to basilar dolichoectasia.
本文报告了一例55岁女性病例，该患者最初突然出现左侧前庭和听力功能丧失，3天后右侧功能也出现丧失。未出现其他神经症状。血管造影和磁共振成像扫描显示椎基底动脉延长扩张症，基底动脉壁上附着有血栓。抗凝治疗使右侧听力功能有足够改善，能够进行对话。前庭器官对冷热试验仍无反应。本文将这种双侧第八神经功能丧失作为基底动脉延长扩张症导致双侧迷路动脉缺血的罕见病例进行讨论。
