Coronal T2-weighted magnetic resonance imaging (MRI) has been reported to be a useful technique for the localization of both spontaneous and traumatic CSF (cerebro spinal fluid) fistulae. We reviewed the magnetic resonance imaging (MRI) scans of 50 patients with temporal lobe epilepsy in whom such sequences were routinely acquired to determine if this asymptomatic population fulfilled any of the criteria for the diagnosis of a CSF fistula. We found that a large proportion did and conclude that using MRI as the initial radiological investigation in the localization of CSF fistulae is of such low specificity that it is of little or no value.
据报道，冠状位T2加权磁共振成像（MRI）是一种用于定位自发性和外伤性脑脊液（CSF）瘘的有用技术。我们回顾了50例颞叶癫痫患者的磁共振成像（MRI）扫描，这些患者常规进行了此类序列扫描，以确定这个无症状人群是否符合脑脊液瘘诊断的任何标准。我们发现很大一部分患者符合，因此得出结论，将MRI作为脑脊液瘘定位的初始影像学检查，其特异性很低，几乎没有价值。
