Advanced Vestibular Schwannoma: A Case of Optic Disc Oedema without Hydrocephalus.

ABSTRACT

A wide range of pathologies can cause papilloedema. Vestibular schwannoma is a benign and slow-growing tumour that causes symptoms and findings on ophthalmic examination when the diagnostic is delayed. The authors report a case of a 64-year-old male who presented with bilateral disc oedema secondary to a vestibular schwannoma grade 4. Obstructive hydrocephalus was not evident. The authors suggest that cerebrospinal fluid protein may have a role in the formation of optic disc oedema. A right suboccipital craniectomy was performed to remove the tumour, leading to secondary facial palsy.
