  【摘要】 目的 肥厚性硬脑膜炎(hypertrophiccranialpachymeningitis,HCP)属罕见疾病,易被误诊,报告1例耳源性肥厚性硬脑膜炎伴颞叶水肿及器质性精神障碍的病例,希引起共同注意。方法 患者男性,26岁,以右侧剧烈头痛、眩晕、恶心、呕吐、面神经及外展神经麻痹等,于1997年7月入院。磁共振成像及CT检查提示颞骨炎性病变,岩尖硬脑膜及其相邻的小脑幕增厚,明显强化呈条带状。诊断为右侧周围性面瘫、迷路炎、岩尖综合征。手术行面神经减压、迷路切除、乳突及岩锥炎性气房清除、岩尖病变探查等。术后除耳聋以外所有症状消失。术后9个月后,患者出现精神异常,曾住精神病院未获改善。1998年5月13日复查磁共振并增强扫描,发现右中颅窝的硬脑膜及小脑幕增厚,颞叶下极明显水肿,海绵窦壁增厚,包围颈内动脉使之受压变小。结果 耳源性HCP伴颞叶水肿及器质性精神障碍的诊断确定,大剂量青霉素静脉点滴治愈。23个月后随访患者生活工作良好,未见复发。结论 MRI是诊断耳源性HCP的主要手段,抗生素治疗此例HCP有效。

  1966年德国人Birkner等[1]首先报告1例硬脑膜出血性硬脑膜炎及硬脑膜下血肿伴广泛钙化的病例。至今各种肥厚性硬脑(脊)膜炎(hypertrophiccranialpachymeningitis,HCP;hypertrophicspinalpachymeningitis,HSP)的有关文献共170篇,其中以日本报告最多。我国毛文萍等[2]1998年曾报告HCP和HSP各1例。硬脑(脊)膜炎包括发生于颅内的HCP和发生于脊髓的HSP,有的患者兼有HCP和HSP。HCP的病因多种多样,涉及多学科。经多方检查,病
