Bilateral vision loss as first presentation of vestibular schwannoma

Abstract

Vestibular schwannoma is a benign, slow-growing tumor of the vestibular nerve, located at cerebellopontine angle. It is derived from the Schwann cells of the myelin sheath of cranial nerve eight. We present here a unique case of vestibular schwannoma, who visited us with a primary complaint of bilateral decreased vision. Detailed examination revealed bilateral papilloedema associated with right-sided cranial nerve five and eight involvements. Patient was operated for the right-sided cerebellopontine angle tumor under intraoperative neuromonitoring. Postoperatively, patient showed significant improvement, both symptomatically and clinically.
