摘要
目的探讨急性一氧化碳中毒后迟发性脑病的临床表现和影像学特点及其诊断价值。方法回顾性对23例急性一氧化碳中毒后迟发性脑病的临床表现和影像学特点进行归纳和分析。结果23例患者中智能障碍23例(100%),言语功能障碍17例(73.9%),另有共济失调精神障碍帕金森综合症及尿失禁等。头部CT和MRI主要表现为皮层下脑白质异常信号及基底节区或苍白球区异常信号,极少累及大脑皮质脑干和小脑。结论急性一氧化碳中毒后迟发性脑病的诊断主要依靠病史和临床症状,MRI比CT更有诊断价值。
Objective To evaluate clinical and imaging characteristics of Delayed eneephalopathy after acute carbon monoxide poisoning（DEACMP） . Methods A retrospective analysis of neurological manifestations and neureimaging findings were conducted in 23 patients with DEACMP . Results The main clinical manifestations of the disease were intellectual disturbance . 100% patients got intellectual disturbance,73,9% laloplegia, and the ataxia mental disorder parkinson＇s syndrome and uroclepsia were also relatively common. CF and MRI scan in DEACMP were observed within bilateral, subcartical cerebral white matter, prominently within bilateral or unilateral globus pallidus or basal ganglia areas, showed high signal intensity in T2 - weighted and low signal intensity in T1 - weighted, The chronic ischemia changes were found in the globus pallidus or basal ganglia areas. Cerebral cortex lesions brain stern cerebellum were observed occasionally. Conclusion The diagnosis of DEACMP mainly depends on case history, clinical features and neuroradiological presence, MRI is more valuable in diagnosis and differential diagnosis than CT.
