# Bilateral Blindness in a Patient With Vestibular Schwannoma and Empty Sella Syndrome: A Case Report

## TL;DR

A rare case of a brain tumor causing blindness and other neurological issues is reported, highlighting the importance of early surgical treatment.

## Contribution

The paper presents a rare association of vestibular schwannoma with bilateral blindness and empty sella syndrome.

## Key findings

- The patient had a T4b vestibular schwannoma causing brainstem and fourth ventricle compression.
- Radical microsurgery achieved gross-total tumor removal with partial facial nerve preservation.
- Visual deficits persisted despite successful tumor removal and resolution of hydrocephalus.

## Abstract

We report a rare clinical presentation of a T4b vestibular schwannoma causing severe compression of the brainstem and fourth ventricle, associated with obstructive hydrocephalus and empty sella syndrome, in a patient presenting with profound neurological and ophthalmological deficits, most notably complete bilateral blindness. Radical microsurgical resection was achieved via a lateral suboccipital (retromastoid) approach, resulting in gross-total tumor removal with preservation of most cranial nerves. Postoperatively, the patient developed House-Brackmann grade III facial palsy. Hydrocephalus resolved without the need for cerebrospinal fluid diversion, gait instability improved, and visual deficits persisted. This case highlights the exceptional association of vestibular schwannoma with bilateral blindness and empty sella syndrome, emphasizing the importance of early recognition and timely surgical intervention in advanced tumors to minimize morbidity and optimize outcomes.
