This report offers a description of typical changes seen on gadolinium-enhanced magnetic resonance (MR) imaging of the entire spine that indicate spontaneous intracranial hypotension (SIH). To the authors' knowledge, this is the first report of its kind. They describe three cases of SIH that were accompanied by dural enhancement throughout the neuraxis on imaging, with the evolution of associated subdural and epidural fluid collections in the spine. Recognition of this disorder is important to be able to distinguish it from an infectious or neoplastic process in which surgical intervention might be warranted. Evaluation using gadolinium-enhanced cranial and spinal MR imaging in patients with postural headaches and an (111)In-labeled cerebrospinal fluid leak study are discussed. Treatment with an epidural blood patch is shown to be particularly effective, with resolution of the radiological and clinical findings.
本报告描述了钆增强磁共振（MR）成像显示的全脊柱典型变化，这些变化提示自发性颅内低压（SIH）。据作者所知，这是此类的首例报告。他们描述了3例SIH病例，成像显示整个神经轴硬脊膜强化，同时脊柱内硬膜下和硬膜外积液演变。认识这种疾病对于将其与可能需要手术干预的感染或肿瘤性病变相鉴别很重要。讨论了对体位性头痛患者使用钆增强头颅和脊柱MR成像进行评估以及（111）铟标记脑脊液漏检查。结果显示，硬膜外血贴治疗特别有效，影像学和临床症状均得到缓解。
