Cerebrospinal fluid rhinorrhea (CSF leaking out of the nose) following a traumatic injury is classified as immediate (within 48 hours) or delayed. Of patients with delayed CSF leaks, 95% present within 3 months after the injury. Most patients with an injury causing CSF leaks are identified within 48 hours.
