A 36-year-old Japanese woman was admitted to our hospital, because of facial palsy, ophthalmoplegia, cerebellar ataxia, and rhythmic myoclonus of the neck. About a few weeks before admission, she developed symptoms of common cold and general fatigue. Her laboratory data were unremarkable, and her CSF was normal. Serum levels of antibodies to gangliosides were within normal limits. Her MRIs of the brain and neck were normal. Both somatosensory evoked cortical potential study and auditory evoked brainstem response study were normal. She was diagnosed as postinfectious brainstem encephalitis, and the administration of corticosteroid was started. After the treatment, her symptoms improved. To our knowledge, it is rare to see myoclonus to the neck without palatal tremor in patients with brainstem encephalitis.
一名36岁的日本女性因面部麻痹、眼肌麻痹、小脑共济失调和颈部节律性肌阵挛入住我院。入院前几周，她出现了普通感冒和全身疲劳的症状。她的实验室检查数据无异常，脑脊液也正常。神经节苷脂抗体血清水平在正常范围内。她的脑部和颈部核磁共振成像均正常。体感诱发电位皮层研究和听觉诱发电位脑干反应研究均正常。她被诊断为感染后脑干脑炎，并开始使用皮质类固醇进行治疗。治疗后，她的症状有所改善。据我们所知，脑干脑炎患者中罕见颈部肌阵挛而无腭部震颤的情况。
