Spontaneous intracranial hypotension (SIH) is an infrequent cause of daily persistent orthostatic headache with an incidence of 5 to 100,000 persons/year. In very rare cases, no cause can be found and these conditions may be called spontaneous cerebrospinal fluid leak (CSFL). Radionuclide cisternography (RNC) has played useful role in detecting CSFL. Although RNC has been used in many cases, few have been reported in which CSFL out of the subarachnoid space was detected. A case of CSFL confirmed by RNC direct findings is reported. SIH is difficult to diagnose and 95% of patients may initially receive an incorrect diagnosis. RNC has been shown to be fairly characteristic in SIH patients.
自发性颅内低压（SIH）是每日持续性直立性头痛的罕见病因，发病率为每年5至10万人。在极少数情况下，找不到病因，这些情况可能被称为自发性脑脊液漏（CSFL）。放射性核素脑池造影（RNC）在检测CSFL中发挥了有益作用。尽管RNC已被用于许多病例，但很少有报告检测到蛛网膜下腔以外的CSFL。本文报告1例经RNC直接检查结果确诊的CSFL病例。SIH难以诊断，95%的患者最初可能会被误诊。RNC在SIH患者中已显示出相当的特征性。
