Abstract
A 30-year-old male patient presented with chronic spontaneous cerebrospinal fluid (CSF) rhinorrhea. He had sustained a mild head injury in childhood. Magnetic resonance imaging of the brain showed aqueductal stenosis associated with moderate supratentorial hydrocephalus, and erosion of the cribriform plate. Following insertion of ventriculoperitoneal shunt, the CSF rhinorrhea completely ceased and no direct repair of the CSF fistula was necessary. Long-standing spontaneous CSF rhinorrhea indicates the possibility of concurrent intracranial pathology, such as aqueductal stenosis.
