Bilateral severe-profound hearing loss. Internal Auditory Canals: There is marked deficiency of the bilateral cochlear and inferior vestibular nerves associated with stenosis of the cochlear apertures. The bilateral facial and superior vestibular nerves appear to be intact. There is fluid within the bilateral mastoid air cells and middle ears. The bilateral semicircular canals, vestibules, and endolymphatic ducts are otherwise grossly unremarkable.Brain: There mild prominence of the subarachnoid spaces anteromedial to the bilateral temporal lobes. Otherwise. there is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. There is an expected degree of myelination. There is no abnormal intracranial enhancement. The ventricles are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is scattered paranasal sinus mucosal thickening.
