Superior semicircular canal dehiscence syndrome (SSCDS) is a rare and recently described inner ear lesion presenting with disequilibrium and associated with dehiscence of the bony covering of SSC. SSCDS patients may present with a variety of vestibular or auditory symptoms or both. The diagnosis of SSCDS depends on the demonstration of a defect in the bony wall of the roof of SSC. A high-resolution computed tomography is helpful for diagnosis. It is usually treated by plugging of dehiscence. We hereby present a rare cause of disequilibrium and SSCDS, diagnosed by clinical presentations, audiological tests and imaging.
