Right sensorineural hearing loss. Internal Auditory Canals: 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. The bilateral mastoid air cells and middle ears also appear unremarkable.Brain: There are numerous scattered areas of predominantly subcortical T2 hyperintensity with a faint striated pattern, suggestive of slightly prominent perivascular space. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is no abnormal intracranial enhancement. 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. Numerous areas of predominantly subcortical white matter T2 hyperintensity likely represent terminal zones of myelination. Nevertheless, follow up MRI in approximately one year may be useful, if clinically warranted.2. No evidence of retrocochlear or inner ear lesions.
