We report a case of a 50-year-old woman in which contrast-enhanced fluid-attenuated inversion recovery (FLAIR) was used for the diagnosis of idiopathic cerebrospinal fluid rhinorrhea. The pre- and postcontrast FLAIR subtraction images showed a contrasted protrusion of the right olfactory cleft canal, highlighting the potential practicality and effectiveness of using pre- and postcontrast FLAIR subtraction images in diagnosing idiopathic cerebrospinal fluid rhinorrhea, in conjunction with conventional high-resolution computed tomography and magnetic resonance cisternography. The successful diagnosis of cerebrospinal fluid rhinorrhea allowed for treatment through endoscopic nasal surgery to close the fistula with a positive clinical outcome.
我们报告了一例50岁女性病例，其中使用对比增强液体衰减反转恢复序列（FLAIR）诊断特发性脑脊液鼻漏。对比增强前后的FLAIR减影图像显示右侧嗅裂管有对比增强的突出，突出了对比增强前后的FLAIR减影图像结合传统高分辨率计算机断层扫描和磁共振脑池造影在诊断特发性脑脊液鼻漏中的潜在实用性和有效性。脑脊液鼻漏的成功诊断使得能够通过鼻内镜手术闭合瘘口，临床结果良好。
