Idiopathic Cerebrospinal Fluid Rhinorrhoea (An Uncommon Diagnosis): A case report and a Review of the Literature.

Cerebrospinal fluid (CSF) rhinorrhoea is often seen among head injured patients from road traffic crashes or physical assault, and sometimes it is a complication of nasal surgical procedures. Intracranial tumours may also result in CSF leakage. Blood stained rhinorrhoea often occur at the time of initial insult or injury, while CSF rhinorrhea may be a delayed manifestation.
