Figure 1: HRCT of temporal bone. The cystic cochlea and vestibule together give a "figure-of-eight" appearance. The cochlea (line arrow) has a featureless single cavity due to complete absence of modiolus and interscalar septa. The vestibule (zigzag arrow) is grossly dilated. The lateral semicircular canal (curved block arrow) is dysplastic and dilated. The cribriform plate (straight block arrow) between the cochlea and internal auditory canal is deficient and the IAC is dilated. However, the vestibular aqueduct (right angled block arrow) is normal. The left tympanum and the mastoid air cells (star) are filled with soft tissue density, indicating CSF leakage. The right tympanum and mastoid are normal (air density)
