摘　　要：目的探讨自发性低颅压综合征(SIH)与肥厚性硬脑膜炎(HCP)的临床及影像学特点,以提高诊断及鉴别能力。方法回顾性分析20例SIH患者及6例HCP患者的临床及影像学资料并进行对比。结果两组患者均以头痛为主要临床表现,SIH患者的头痛多与体位改变有关,脑脊液压力明显低于正常,HCP患者除头痛之外,多组颅神经损害较SIH更为常见。影像学上两组均可表现为硬脑膜弥漫性增厚并异常强化,但HCP硬脑膜强化可为局限性,部分病例可见邻近部位感染灶,而SIH可出现硬膜下积液。结论自发性低颅压综合征与肥厚性硬脑膜炎有一定的相似之处,但在临床及影像学上均有各自的特点,应注意鉴别。Objective To assess the differences between spontaneous intracranial hypotension（SIH） and hypertrophic cranial pachymeningitis（HCP） on clinical and imaging characteristics. Methods The clinical and imaging data of 20 patients with SIH and 6 patients with HCP was investigated. Results Both of SIH and HCP were characterized by headache, thickened and enhancement dura. SIH was characterized by postural headache,low CSF pressure and subdural collection of fluid. Multiple cranial nerve impairment, focal thickened dura and adjacent focal site infection were found in some HCP patients. Conclusions Although there are simi larities in clinical and imaging features,attention should be paid to differentiate SIH and HCP.
