- Abstract
Objectives: Cystic dilation is formed by the fusion of the structures that make up this area, and its is one of the anomalies of the inner ear. Apart from the anomalies identified in the literature, cochlea is normal in our case and isolated vestibular cystic dilation is seldom described. We aimed to present the anatomical structure of isolated vestibular cystic dilation seen in this case, its relation with other structures, radiological features. Case: 42-year-old female patient's right temporal bone computed tomography images were examined at Selcuk University Medical Faculty. In case, cystic dilation was determined by losing the normal anatomical structures of vestibulum and lateral semicircular canal, with its axial size measured at about 6x6 mm. The right side cochlea, anterior and posterior semicircular canals were observed to be normal. Conclusion: A series of bone labyrinth anomalies occur as the inner ear stops at different stages of development of the bone segment. Usually, vestibular malformations are associated with cochlear malformations in these anomalies, however in our case isolated vestibulum and lateral semicircular canal were participated. The anomaly is often bilaterally, but in case seen unilaterally. We think this rare anomaly will benefit anatomists, radiologists and clinicians.
