Intracranial hypotension (IH) is an uncommon, benign, and usually self-limiting condition caused by low cerebrospinal fluid (CSF) pressure, usually due to CSF leakage. The dominant clinical finding is an orthostatic headache. Other common clinical features include fever, nausea, vomiting, and tinnitus. Magnetic resonance imaging (MRI) plays an important role in the diagnosis and follow-up of patients with IH. Specific MRI findings include intracranial pachymeningeal enhancement, sagging of the brain, pituitary enlargement, and subdural fluid collections. Intracranial hypotension can mimic other conditions such as aseptic meningitis or pituitary adenomas. Differential diagnosis is important, because misdiagnosis may lead to unnecessary procedures and prolonged morbidity.
颅内低压（IH）是一种不常见的、良性的且通常为自限性的疾病，由脑脊液（CSF）压力降低引起，通常是由于脑脊液漏所致。主要的临床症状是体位性头痛。其他常见的临床特征包括发热、恶心、呕吐和耳鸣。磁共振成像（MRI）在颅内低压患者的诊断和随访中起着重要作用。MRI的特异性表现包括颅内硬脑膜强化、脑下垂、垂体增大和硬膜下积液。颅内低压可能会与其他疾病相似，如无菌性脑膜炎或垂体腺瘤。鉴别诊断很重要，因为误诊可能导致不必要的检查和延长发病时间。
