Abstract
|
|
|
|
A 25-year-old woman presented with atypical dizziness with oscillopsia. The neuro-otological evaluations showed bilateral vestibulopathy with mild sensorineural hearing loss. Computed tomography and magnetic resonance imaging demonstrated bilateral isolated lateral canal dysplasia (LSCD) with normal cochlea. LSCD is relatively common inner ear malformation, but it is rarely found in bilateral vestibulopathy. In case of patients with bilateral vestibulopathy who cannot find the cause, should be considered conducting radiological examinations in mind of the inner ear anomalies.
