- Although classical benign paroxysmal positional vertigo (BPPV) has generally been resolvable by routine manual repositioning maneuvers, nevertheless resistant cases and variant remain a significant problem. Recently, we experienced a case of posterior semicircular canal BPPV combined with changes to various types of BPPV during manual reposition maneuver and vestibular neuritis. We examined her brain MRI due to low response of routine manual reposition maneuvers and frequently recurrence of BPPV. In brain MRI, we found 1.3cm sized mass in hypoglossal canal. It seemed to be neuroma on hypoglossal nerve. A refractory BPPV poses problems of pathophysiogenetic interpretation, differential diagnosis with a CNS lesion and therapeutic strategy. We thought that refractory BPPV should be treated with more frequently examination and manual repositional maneuver and distinguished from CNS lesion.
