| ABSTRACT |
|
Benign paroxysmal positional vertigo (BPPV) is the most common disease of the peripheral vestibular
disorder. Recently, many cases of posterior and lateral canal BPPV were reported. But there are few cases
about superior canal BPPV, particularly about cupulolithiasis. The incidence of superior semicircular canal
BPPV was reported about 3%. We report a 49-year-old man who showed counter-torsional downbeat
nystagmus in left side Dix-Hallpike position. The nystagmus was continued for 3 minutes and the
symptoms were eventually relieved after reversed Epley maneuver.
Key Words : Cupulolithiasis, superior semicircular canal |
