Abstract

Cranial CSF leaks may be difficult to recognize in the clinical or subacute setting, and are important to identify following traumatic injury. Management will vary depending on the etiology and severity of the leak. Clinicians in both the primary care and emergency care setting will benefit from understanding the various etiologies of these leaks, important symptoms and comorbidities to consider on patient presentation, and how they can affect management. Although a majority of CSF leaks will resolve with conservative management, spontaneous leaks that remain untreated can place certain patient populations at risk for infection. This article reviews the causes of cranial CSF leaks and outlines recommendations for conservative versus surgical treatment based on patient presentation.

Diagnosis and Management of Cranial Cerebrospinal Fluid (CSF) Leaks

Cranial CSF leaks may be difficult to recognize in the clinical or subacute setting, and are important to identify following traumatic injury. Management will vary depending on the etiology and severity of the leak. Clinicians in both the primary care and emergency care setting will benefit from understanding the various etiologies of these leaks, important symptoms and comorbidities to consider on patient presentation, and how they can affect management. Although a majority of CSF leaks will resolve with conservative management, spontaneous leaks that remain untreated can place certain patient populations at risk for infection. This article reviews the causes of cranial CSF leaks and outlines recommendations for conservative versus surgical treatment based on patient presentation.
