Left hearing loss. The left lateral semicircular canal appears to be mildly dysplastic along with a relatively small semicircular canal bone island. Otherwise, the rest of the left inner ear structures and the right inner ear structures are unremarkable. The bilateral internal auditory canals including the vestibulocochlear nerves are unremarkable. The bilateral cerebellopontine angles are intact as well. The petrous apices and temporal bones appear unremarkable. The imaged portions of the brain are normal. There is no evidence of tumors.
