A 25-year-old female veterinarian presented with 1-week of flu-like symptoms followed by progressive encephalopathy. She was originally from Nicaragua and had been in the USA for 4 months. In the emergency department, she was confused and non-verbal with meningismus and facial myoclonus, but with an otherwise non-focal neurological exam. MRI brain abnormalities were consistent with viral encephalitides. Influenza B was detected via nasopharyngeal swab PCR. Mental status improved rapidly with oseltamivir. In such presentations, especially during flu season, influenza encephalitis must be considered, to facilitate early recognition of this entity and allow for targeted treatment.

一名25岁的女性兽医出现1周的流感样症状，随后进行性脑病。她最初来自尼加拉瓜，已经在美国待了四个月。在急诊科，她被脑膜炎和面部肌阵挛弄糊涂了，没有口头表达，但是还接受了非重点神经系统检查。MRI脑部异常与病毒性脑炎一致。通过鼻咽拭子PCR检测到乙型流感。奥司他韦的精神状态迅速改善。在此类情况下，尤其是在流感季节，必须考虑流感脑炎，以促进对该实体的早期识别并进行针对性治疗。
