BACKGROUND
Upper limbs dysmetria caused by spinal cord injury is very rare. We will discuss the associated mechanism in our articles.
CASE PRESENTATION
A 51-year-old male had sudden onset of weakness, dysmetria over bilateral upper limbs and ataxia after he fell accidentally. Brain magnetic resonance imaging (MRI) revealed no specific findings. C-spine MRI revealed C1 myelopathy and C4-6 spinal cord compression by bulged disc. The symptoms subsided after surgical intervention.
CONCLUSION
Sudden onset of upper limbs dysmetria is a sign of dysfunction in cerebellum and its associated pathway. However, lesion in spinal cord can also cause cerebellar signs such as dysmetria.
背景
脊髓损伤导致的上肢辨距不良非常罕见。我们将在文章中讨论相关机制。
病例报告
一名51岁男性在意外摔倒后突然出现双侧上肢无力、辨距不良和共济失调。脑部磁共振成像（MRI）未发现特异性表现。颈椎MRI显示C1脊髓病和C4 - 6椎间盘膨出压迫脊髓。手术干预后症状缓解。
结论
上肢辨距不良突然发作是小脑及其相关通路功能障碍的迹象。然而，脊髓病变也可导致小脑体征，如辨距不良。
