1965年Fisher曾命名本综合征为同侧共济失调和下肢轻瘫,1978年同著者又将此综合征改为共济失调性偏瘫。其特征为一侧肢体既有锥体束损伤的症状又有小脑症状。这在常见的神经病学的体征上讲是不符合的。我们遇到4例均由腔隙性梗塞引起,报告如下: 例1,男性,41岁。左侧肢体共济失调,跟膝胫试验不稳准,左侧轻偏瘫.Babinski氏征阳性,左侧肢体麻木,语言障碍,颅神经正常。CT扫描显示右侧侧脑室外下方及右侧基底节处各有腔隙性梗塞灶一个。例2.男性,52岁。左侧肢体轻偏瘫,肌力Ⅳ级,左侧Babinski氏征阳性。左侧鼻唇淘浅,伸舌偏左,Romberg征(+),高血压史7年。CT扫描显示右侧内
In 1965 Fisher had named the syndrome as ipsilateral ataxia and lower extremity paresis, in 1978 with the same author and the syndrome to ataxia hemiplegia. It is characterized by the symptoms of pyramidal tract injury and cerebellar symptoms on one limb. This is not consistent with the usual neurological signs. We encountered four cases caused by lacunar infarction, the report is as follows: Example 1, male, 41 years old. Left limb ataxia, unstable with the knee shin test, left hemiparesis lightly.Babinski’s sign positive, left limb numbness, speech impairment, normal cranial nerves. CT scans showed that there was one lacunar infarct in each of the right and left inferior basal ganglia. Example 2. Male, 52 years old. Hemiplegia on the left limb, muscle strength grade IV, Babinski’s sign on the left positive. The left side of the nose Amoy shallow, leaning tongue left, Romberg sign (+), history of hypertension for 7 years. The CT scan shows inside the right side
