ABSTRACT |
Congenital inner ear malformations are frequently found in patients with sensorineural hearing loss, but isolated vestibular anomalies with normal cochlear development have been rarely reported. We report a 20-year-old man with recurrent dizziness and disequlibrium without hearing impairment. Neuro-otological evaluations showed a left peripheral vestibulopathy with normal hearing function. Three dimensional volume rendering image using magnetic resonance constructive interference in steady state sequence demonstrated isolated vestibular anomalies involving bilateral horizontal semicircular canals. Isolated vestibular anomalies might not be as rare as previously thought among patients with recurrent dizziness, and should be carefully evaluated through various imaging techniques |
