Curing Benign Paroxysmal Positional Vertigo in Patients With Brain Tumor: Case Series and Literature Review

Benign paroxysmal positional vertigo (BPPV) is a common vestibular disorder. It accounts for a third of all vestibular disorders diagnosed in the general population and is usually diagnosed and treated successfully. This article presents two cases of BPPV in a 52-year-old man and a 45-year-old patient, respectively. Both patients presented with recurrent episodes of vertigo associated with certain head movements. Medical history for the first patient included surgery for acoustic neuroma 12 months before developing the vertigo episodes. The second patient underwent a neurosurgical operation for glioblastoma multiforme (GBM) followed by radiotherapy three months before this presentation. Both patients were diagnosed with right-sided posterior canal BPPV after the Dix-Hallpike test. Their symptoms completely resolved within few minutes of the Epley maneuver. These cases highlight the importance of diagnosing and treating a potentially curable condition that can coexist in some patients with brain tumors.
