A 57-year-old man was admitted because of left hemiparesis. A magnetic resonance imaging scan of the brain revealed a recent infarct from the dorsal side of the right putamen to the corona radiata. Three hours after onset, he complained of rotational vertigo. Truncal ataxia was also found on standing a few days later, which persisted until the chronic phase. Repeat magnetic resonance imaging scans on days 2 and 11 revealed no additional lesions. The present case indicates that rotational vertigo might result from a small, supratentorial, subcortical lesion.
一位 57 岁男性因左侧偏瘫入院。脑部磁共振成像扫描显示右侧壳核背侧至放射冠有近期梗死灶。发病后 3 小时，他主诉出现旋转性眩晕。几天后，站立时还发现躯干性共济失调，且一直持续到慢性期。发病第 2 天及第 11 天的重复磁共振成像扫描未显示其他病灶。本例表明，旋转性眩晕可能是由较小的、幕上、皮质下病变引起的。
