Progressive and congenital hearing loss. Internal Auditory Canal: The bilateral cranial nerve 7 and 8 complexes are intact. There is no evidence of mass lesions. The inner ear structures, including the cochlea, vestibule, endolymphatic duct, and semicircular canals, appear unremarkable. There is scattered fluid signal in the right mastoid air cells and middle ear. Brain: There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are terminal zones of myelination in the bilateral parietal lobes. The brain parenchyma otherwise appears unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1. No evidence of cochlear nerve deficiency of gross inner ear anomalies.2. No evidence of acute intracranial hemorrhage, mass, or acute infarct.3. Scattered fluid signal in the right mastoid air cells and middle ear likely represents sequela of recent otomastoiditis.
