Bilateral sensorineural hearing loss IACNo abnormal foci of enhancement are appreciated within the internal auditory canals. The cochlea and semicircular canals appear intact. The cochlear nerve can be followed bilaterally tracking into the cochlea. The modiolus is well formed bilaterally.No abnormal enhancing lesions are appreciated at the cerebellopontine angle cisterns nor the internal auditory canals.There is signal hyperintensity present within the left middle ear and mastoid air cellsBRAINThe CSF spaces are appropriate for the patient's stated age with no midline shift. Myelination pattern is age-appropriateNo abnormal enhancing mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are underdeveloped and partially opacified. The visualized portions of the orbits are intact.
1.There is opacification of the left middle ear and mastoid. Etiology cannot be established on this exam.2.If there is persistent clinical suspicion for congenital abnormality involving the inner ear structures and temporal bone CT may be helpful.3.No abnormal lesions are appreciated within the brain parenchyma
