Cerebrospinal fluid rhinorrhoea: Unusual presentation of acoustic neurinoma

Abstract
A 40-year-old male presenting with spontaneous cerebrospinal fluid (CSF) rhinorrhoea was found to have raised intracranial pressure due to an acoustic tumour. This report adds to the scant literature on an intracranial tumour causing markedly raised intracranial pressure leading to a non-traumatic CSF rhinorrhoea. After a ventricular shunt and resection of the tumour the CSF leak stopped.
