Anterior skull base cerebrospinal fluid (CSF) fistulas result from skull base osteodural defects, allowing subarachnoid space CSF to escape into pneumatized cavities such as the paranasal sinuses and nasal fossa. Precise localization, characterization, and effective treatment of CSF leaks is essential to prevent meningitis, treatment failure, or recurrence. Advances in magnetic resonance imaging have improved radiologists' ability to localize and characterize anterior skull base CSF fistulas. This article reviews new imaging techniques enabling diagnostic location of CSF fistulas, with an emphasis on magnetic resonance imaging-based techniques.
前颅底脑脊髓液（CSF）瘘是由于颅底骨硬脑膜缺损引起的，使蛛网膜下腔的 CSF 逸入鼻窦和鼻腔等含气腔隙。准确定位、定性和有效治疗 CSF 漏对于预防脑膜炎、治疗失败或复发至关重要。磁共振成像的进步提高了放射科医生定位和定性前颅底 CSF 瘘的能力。本文综述了新的成像技术，这些技术能够帮助诊断 CSF 瘘，并重点介绍了基于磁共振成像的技术。
