Figure 5: Cystic cochleo-vestibular malformation. (a and b) High resolution computed tomography axial images shows cystic dilated vestibule (thin black arrow) with widened basal cochlear turn (thick black arrow). Internal auditory canal (thick white arrow) and vestibular aqueduct are normal in size. (c) Magnetic resonance maximum intensity projection image show enlarged vestibule with dysplastic dilated basal turn of cochlea with nonvisualization of middle and apical turns with absent modiolus
