AN UNUSUAL CAUSE OF BENIGN PAROXYSMAL POSITIONAL VERTIGO

Benign paroxysmal positional vertigo (BPPV) is a self-limiting conditi on characterized by vertigo and nystagmus induced by certain head posi tions. The most common causes of BPPV are post-traumatic following hea d injury and post-viral labyrinthitis. We present an interesting case of BPPV following an otherwise uneventful neurosurgical removal of a p arietal osteoma using hammer and chisel. Caution should be exercised d uring such procedures as disabling vertigo can result for a considerab le period of time.
