A 73-year-old woman with essential hypertension and diabetes mellitus abruptly developed astasia. There were no other neurological abnormalities. Cranial diffusion-weighted magnetic resonance imaging demonstrated a localized infarction in the right-sided suprathalamic white matter. Under antiplatelet agent and rehabilitation, the patient became asymptomatic within 4 days. This is a first reported case of isolated astasia due to a suprathalamic white matter infarction. We speculated that disruption of the connection from the ventrolateral nucleus of the thalamus to the posterior cingulate gyrus and/or supplementary motor area might cause astasia.
一名73岁患有原发性高血压和糖尿病的女性突然出现起立不能。无其他神经功能异常。头颅扩散加权磁共振成像显示右侧丘脑上白质局限性梗死。在使用抗血小板药物并进行康复治疗后，患者在4天内无症状。这是首例因丘脑上白质梗死导致孤立性起立不能的报道病例。我们推测，从丘脑腹外侧核到后扣带回和/或辅助运动区的连接中断可能导致起立不能。
