What is Cerebrospinal Fluid Rhinorrhea?
Cerebrospinal fluid (CSF) rhinorrhea is a condition where CSF, the fluid surrounding the brain, leaks into the nose and sinuses. Common causes include head trauma, sinus or skull base surgery, or increased pressure inside the skull and brain tissue. In some cases, the leak is spontaneous and the cause is unknown. Headache is a common accompanying symptom.
Typical Symptoms of Cerebrospinal Fluid Rhinorrhea
- Injury to the head
- Runny nose
- Bloodstains in mucus
- Nosebleed
- Nose pain
- Changes in sense of smell
Diagnostic Questions for Cerebrospinal Fluid Rhinorrhea
Your doctor may ask these questions to check for this disease:
- Did you injure your head?
- Do you have a runny nose?
- Do you have thin, bloody nasal discharge?
- Do you have a nosebleed?
- Is your nose painful?
Treatment of Cerebrospinal Fluid Rhinorrhea
CSF rhinorrhea from small leaks may only require bed rest and medication. However, spontaneous leaks or leaks due to skull fracture typically need to be repaired by surgery.
