Fig 2. Thirty-four-year-old woman with dizziness. Transverse (A) and coronal (B) MDCT sections of the right temporal bone. Transverse (C) and coronal (D) MDCT sections of the left temporal bone. Bilateral hypoattenuated foci (black arrow) in the anterior otic capsules are particularly well underlined by complete pneumatization of the petrous apex. Otosclerosis was ruled out by other investigations, and these findings were considered as normal variants.
