A case report of cerebrospinal fluid rhinorrhea through the ipsilateral nostril post vestibular schwannoma surgery through retrosigmoid suboccipital approach
Case report describes delayed cerebrospinal fluid rhinorrhea post vestibular schwannoma surgery in a male patient, highlighting surgical management implications.
Key Points
This report aims to highlight a rare case of delayed cerebrospinal fluid rhinorrhea following vestibular schwannoma surgery.
A 45-year-old male underwent right retrosigmoid suboccipital craniotomy for tumor excision.
Post-operative symptoms included intermittent headache and clear nasal discharge, prompting imaging and surgical exploration.
Dural repair was performed with a muscle patch graft and obliteration of mastoid air cells with bone wax.
Imaging revealed a pseudomeningocele with CSF tracking into mastoid air cells.
Surgical exploration confirmed a dural rent leading to rhinorrhea.
Post-surgery, the CSF leak resolved completely after the repair procedure.
