目的讨论中枢神经系统表面铁沉积症的病例特点及诊断。方法对1例患者进行临床相关资料分析。结果中枢神经系统表面铁沉积症是由于铁沉积在中枢神经系统表面而产生。临床典型特征为:进行性感音性听力下降,小脑性共济失调和锥体束征,磁共振的梯度回波序列 T_2~*加权像上可见颅脑及脊髓表面显著低信号带,脑脊液中铁蛋白含量增高。结论中枢神经系统表面铁沉积症容易误诊,通过病史及体格检查并结合相关检查可以在疾病的早期确诊。磁共振的梯度回波序列 T_2~*加权像及脑脊液的相关检查有助于诊断。
Objective To discuss the features and diagnosis of the central nervous system surface iron deposition disease. Methods A case of clinical data analysis. Results Central nervous system surface iron deposition disease is due to iron deposition in the central nervous system surface and produce. Typical clinical features are: sensory hearing loss, cerebellar ataxia and pyramidal tract signs, magnetic resonance gradient echo sequence T_2 ~ * weighted image on the brain and spinal cord surface visible low signal band, ferritin in cerebrospinal fluid Increased content. Conclusion It is easy to misdiagnosis the surface of the central nervous system iron deposition disease, through medical history and physical examination combined with related tests can be diagnosed early in the disease. Magnetic resonance gradient echo sequence T_2 ~ * weighted image and cerebrospinal fluid related tests help to diagnose.
