摘要 【目的】报道长期染发导致中枢神经系统铅中毒的临床和MRI表现。【方法】对5例经血铅检测证实的长期染发导致中枢神经系统铅中毒患者的临床资料进行回顾性分析。【结果】5例患者均为亚急性起病,主要表现为反应迟钝、记忆力下降;头颅MRI示双侧基底节区对称性等T1 长 T1、等 T2 长 T2 异常信号灶。经驱铅治疗后,症状好转、血铅水平下降,磁共振异常信号灶水肿明显减轻。【结论】含铅超标的染发剂是一种新的生活铅中毒来源,长期应用可导致中枢神经系统铅中毒和MRI双侧基底节区对称性改变。 To report the clinical and MRI manifestation of central nervous system lead poisoning due to long-term dyeing.Clinical data of five cases of central nervous system lead poisoning due to long-term dyeing were analyzed retrospectively. The diagnosis were proved by detection of Pb-B.Five cases had subacute onset and the main clinical manifestations were dull and descent of memory. The abnormal signal foci were showwed in the di-basal ganglia on the MRI. After expelling lead, the symptoms were improved, the Pb-B lowered and the abnormal signal foci on the MRI lightened obviously.[Conclusion]The hair dye containing ultra-standard lead is a new source of living lead poisoning.Long-term dyeing may lead to central nervous system lead poisoning and symmetrical MRI changes in the di-basal ganglia.
