We report a case of rheumatoid pachymeningitis involving the posterior fossa. A 71-year-old woman presented with headache, vertigo and dizziness. MRI demonstrated hypertrophic masses in the meninges of the left cerebellar tentorium, cerebellopontine angle and the fourth ventricle. Six months of treatment with betamethasone, prednisolone and azathioprine improved the patient's neurological status. Because an inappropriate immune process and systemic immune disease may cause idiopathic pachymeningitis, the performance of immunological studies for idiopathic cases is mandatory.
我们报告一例累及后颅窝的类风湿性硬脑膜炎。一名71岁女性出现头痛、眩晕和头晕症状。磁共振成像（MRI）显示左侧小脑幕、桥小脑角和第四脑室脑膜有肥厚性肿块。使用倍他米松、泼尼松龙和硫唑嘌呤治疗六个月后患者神经状态有所改善。由于不适当的免疫过程和全身性免疫疾病可能导致特发性硬脑膜炎，因此对特发性病例进行免疫学研究是必要的。
