Overview

What is a cerebrospinal fluid leak?

A cerebrospinal fluid (CSF) leak happens when brain fluid leaks through the coverings of the nervous system. This fluid may drain from the ear or the nose, depending on where the skull bone is damaged, and can cause headaches and other symptoms.

CSF leaks can also happen after an epidural or a lumbar puncture (spinal tap), or because of a skull base tumor, with the fluid draining into the subcutaneous tissue and, in turn, not visible to the patient.

CSF leaks can occur spontaneously for unknown reasons, or because of trauma to the head, brain or spine.

Patients with high CSF pressure causing hydrocephalus, an abnormal accumulation of cerebrospinal fluid, may be at an increased risk of developing CSF leaks.
