Deskripsi
Isolated vestibule-lateral semicircular canal dysplasia (LSCCD) is one of the most common inner ear malformations. We present a case of a 59-year-old patient with right vestibule-lateral canal dysplasia and a history of spontaneous vertigo spells without hearing loss. Vestibular assessment showed a dissociation between caloric responses and vestibulo-ocular reflex gain as measured with the video head-impulse test.
