BACKGROUND
Brachial nerve palsy without sensory impairment is called cervical lower motor neuron syndrome (CLMNS), and differential diagnosis can be difficult.
OBSERVATIONS
A 50-year-old man presented with left brachial nerve palsy (C7, C8, and T1). Neuroradiological imaging findings showed a dural arteriovenous fistula at the cervicothoracic junction. Symptoms were promptly alleviated by direct shunt occlusion via a microsurgical procedure.
LESSONS
Cervical spinal venous malformations presenting with CLMNS are very rare. It is essential to perform a differential diagnosis and determine surgical treatment based on an understanding of vascular anatomy. https://thejns.org/doi/10.3171/CASE25353.
背景
无感觉障碍的臂丛神经麻痹称为颈下运动神经元综合征（CLMNS），鉴别诊断可能困难。
观察结果
一名50岁男性出现左侧臂丛神经麻痹（C7、C8和T1）。神经放射学成像结果显示在颈胸交界处有硬脑膜动静脉瘘。通过显微手术直接封堵分流后症状迅速缓解。
经验教训
表现为CLMNS的颈脊髓静脉畸形非常罕见。基于对血管解剖结构的理解进行鉴别诊断并确定手术治疗至关重要。https://thejns.org/doi/10.3171/CASE25353 。
