目的:探讨延髓背外侧综合征的病因,临床表现,影像学改变,治疗及预后。方法:对我院收治的32例患者临床资料整理并进行回顾性分析。结果:动脉粥样硬是主要病因,临床表现为感觉障碍、眩晕、吞咽困难、恶心呕吐、共济失调、Horner征、水平眼震,可伴有呃逆,复视,对侧肢体轻瘫。影像学改变为延髓背外侧异常信号,合并小脑,桥脑,枕叶,丘脑异常信号。经积极治疗后神经系统症状和体征均有不同程度好转。结论:延髓背外侧综合征综合征系由小脑后下动脉供血障碍所致,典型临床表现有眩晕、交叉感觉障碍、Horner征、吞咽困难、构音障碍和共济失调,头颅MRI检查为首选检查方法。
Objective: To investigate the etiology, clinical manifestations, imaging changes, treatment and prognosis of medullary dorsolateral syndrome. Methods: The clinical data of 32 patients treated in our hospital were collected and analyzed retrospectively. Results: Atherosclerosis was the main etiology. The clinical manifestations were sensory dysfunction, dizziness, dysphagia, nausea and vomiting, ataxia, Horner syndrome, nystagmus, hiccups, diplopia and contralateral limb paresis. Imaging changes to the medullary dorsolateral anomalous signal, merge cerebellum, pons, occipital lobe, hypothalamus abnormal signal. After active treatment of nervous system symptoms and signs have varying degrees of improvement. Conclusion: The medullary dorsolateral syndrome syndrome is caused by the disorder of blood supply to the posterior inferior cerebellar artery. The typical clinical manifestations are dizziness, cross-sensory disturbances, Horner’s syndrome, dysphagia, dysarthria and ataxia. The cranial MRI examination is the first choice method.
