title: Simultaneous acute superior nerve neurolabyrinthitis and benign paroxysmal positional vertigo.
abstract: An acutely vertiginous 47-year-old woman presented to the emergency department with simultaneous acute left neurolabyrinthitis and left posterior canal benign paroxysmal positional vertigo (BPPV). Gaze nystagmus from the neurolabyrinthitis hampered diagnosis of the BPPV. However, once the BPPV was identified and treated, the patient's subjective vertigo improved rapidly. Concomitant BPPV should not be overlooked when a diagnosis of acute neurolabyrinthitis is made in the emergency department.
