 Patchy hypodensity is present within the pons without associated restricted diffusion consistent with chronic small vessel ischemic disease. There is loss of normal flow void within the distal right vertebral artery, with some retrograde reconstitution of the distalmost segment. Fluid is present within a few left mastoid air cells.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.
