Spinal fluid (cerebrospinal fluid or CSF) leaking from the nose is typically clear, resembling water.
Understanding the Appearance of CSF Leaks
When cerebrospinal fluid leaks from the nose, its clear, watery appearance can make it challenging to differentiate from ordinary nasal secretions, especially if the volume is small. This similarity often requires medical evaluation to confirm if a leak is present.
Diagnostic Identification of CSF
To aid in the identification and localization of a CSF leak, medical professionals may use specialized diagnostic techniques. One method involves injecting a fluorescent dye into the CSF space. This dye turns the otherwise clear fluid into a distinct yellow-green color, making the leak much easier to detect and trace. This diagnostic coloring helps healthcare providers confirm the presence of CSF and pinpoint the exact location of the leak for treatment.
