Background: This is the first case to our knowledge of a serious adverse event following the Epley maneuver, which is the treatment of choice for benign paroxysmal positional vertigo (BPPV), the most common vestibular disorder in adults.
Case presentation: A 77 year old female presented for outpatient evaluation of vertigo at a tertiary otolaryngology clinic. She was found to have BPPV clinically, and elected to have a particle repositioning maneuver (Epley maneuver) performed in clinic. Immediately following Epley maneuver, she had severe nausea and vomiting, with evolving visual changes. A CT angiogram of the brain was performed urgently through the emergency department and demonstrated an acute intraparenchymal hemorrhage in the occipital lobe. After medical stabilization and rehabilitation, the patient continues to have a permanent visual field deficit.
Conclusion: The Epley maneuver is safe and effective, and there are no prior reports of serious adverse events associated with its use. This case, in which a patient experienced a hemorrhagic stroke after undergoing the Epley maneuver, is the first and sole case in the medical literature of an Epley-associated serious adverse event. The indirect causation and extreme rarity of this event do not warrant any change to patterns of practice.
