Abstract

Dizziness is a prevalent clinical complaint, and determining the underlying etiology can be challenging. Posterior fossa masses have been observed to cause vertigo, with presentations very similar to Meniere's disease. In this report, we describe a case of a patient who presented with recurrent episodes of Meniere's-like vertigo in the setting of a posterior fossa meningioma, who underwent surgical resection of the tumor with significant improvement postoperatively. We postulate that these symptoms were caused by secondary endolymphatic hydrops and were able to demonstrate improvement in high-frequency vestibulo-ocular reflex with pre- and postoperative video head impulse testing.
