 Images of the internal auditory canals demonstrate the seventh and eighth nerves to be normal in size and symmetric bilaterally without masses or enhancing lesions along the course of these nerves or in the cerebellopontine angle cisterns bilaterally. The inner ear structures are normal in appearance and symmetric bilaterally without congenital inner ear anomalies identified on either side. There are no vascular anomalies.Limited views of the intracranial contents redemonstrate chronic small vessel ischemic disease.
1.Negative MRI of the brain and internal auditory canals including gadolinium enhancement. Specifically, there are no findings to explain the patient's asymmetrical sensorineural hearing loss.2.It should be noted that a vestibular schwannoma was not identified on the comparison MRI from 8/27/2014. For that study, an intradural and extramedullary incidental tiny nodule of apparent enhancement was noted within the cervical spinal canal at the level of C2 which was felt to potentially represent a small schwannoma, although artifact is a consideration.
