Pseudo-cerebrospinal fluid rhinorrhea (PCSFR) is a rare condition mimicking cerebrospinal fluid (CSF) leaks after head trauma. Recognizing PCSFR

Area of Science:

  • Neurology
  • Otolaryngology
  • Neurosurgery

Background:

  • Posttraumatic clear rhinorrhea following skull base injuries can indicate cerebrospinal fluid (CSF) fistula.
  • Autonomic dysfunction is a potential differential diagnosis, specifically pseudo-cerebrospinal fluid rhinorrhea (PCSFR).
  • PCSFR results from injury to parasympathetic fibers innervating the sphenopalatine ganglion, presenting a diagnostic challenge.

Purpose of the Study:

  • To present a case of noniatrogenic posttraumatic PCSFR.
  • To highlight the diagnostic features and management of PCSFR.
  • To emphasize PCSFR as a consideration in patients with skull base trauma.

Main Methods:

  • Case report of a previously healthy patient with noniatrogenic posttraumatic PCSFR after a horseback riding accident.

Related Experiment Videos

  • Review of clinical presentation, diagnostic challenges, and treatment strategies for PCSFR.

    • Main Results:

    • The case illustrates PCSFR as a distinct entity from CSF rhinorrhea.
    • Key features of PCSFR include trauma history, delayed rhinorrhea, decreased lacrimation, and negative beta-2 transferrin test.
    • Management focuses on restoring autonomic homeostasis via topical medications or surgical disruption of parasympathetic fibers.

    Conclusions:

    • PCSFR is a critical differential diagnosis in posttraumatic rhinorrhea.
    • Understanding the autonomic pathway involved is key to diagnosis and management.
    • This entity should be considered in all patients with prior skull base trauma.
