摘要：

自发性低颅压以体位性头痛为主要临床表现，是中枢神经系统少数明确诊断后可治愈的疾病之一，但仍有部分患者头痛发作无典型体位性特点，给临床诊断带来较大困难，也常因误诊、漏诊而延误最佳治疗时机。近年来，影像学技术的日益进步，有助于临床早期诊断，并发展出多种新型治疗方法。本文拟对近年来自发性低颅压的影像学检查和治疗方法进行综述。

Abstract:

Characterized by "postural headche", spontaneous intracranial hypotension (SIH) is one of the few diseases of central nervous system (CNS) that can be completely cured with definitive diagnosis. However, if the headache attacks are not typically postural, it brings doctors much difficulties to diagnose and make more misdiagnosis or diagnostic errors. In recent years, rapidly developed imaging technologies contribute to early diagnosis in clinic and a lot of new treatment methods were emerged. Here we summarize the literatures about imaging and treatment methods in the past few years to help doctors increase the understanding of SIH.
