Symptoms
clear, colourless liquid draining from nose
Complications
infection
Causes
basilar skull fracture

other types of rhinorrhoea
Treatment
conservative management: observation
neurosurgery: repairing any skull fracture
Cerebrospinal fluid rhinorrhoea (CSF rhinorrhoea) refers to the drainage of cerebrospinal fluid through the nose (rhinorrhoea). It is typically caused by a basilar skull fracture, which presents complications such as infection. It may be diagnosed using brain scans (prompted based on initial symptoms), and by testing to see if discharge from the nose is cerebrospinal fluid. Treatment may be conservative (as many cases resolve spontaneously), but usually involves neurosurgery.
