摘要

Vertical nystagmus occurs in patients with central vestibular system pathology. Lesions of the pons, medulla, and cerebellum lead to vertical nystagmus. Given this association, vertical nystagmus is considered pathognomonic in nature. We present a case of benign paroxysmal positional vertigo (BPPV) with positive Dix-Hallpike bilaterally, but also with upbeat purely vertical nystagmus in the straight back head hanging position. Computed tomography imaging of the typically pathologic structures in vertical nystagmus (brainstem/posterior fossa) revealed normal anatomy. We propose this case as an instance of peripheral-associated purely vertical nystagmus without central pathology, while building on our previous understanding of BPPV physiology.
