Diagnosis: Tinnitus, bilateral Sensorineural hearing loss, unilateral, right ear, with unrestricted hearing on the contralateral sideClinical question: evaluated IACs, asymmetrical SNHL (Right) on AudiogramSigns and Symptoms: Right ear tinnitus, Asymmetrical SNHL No 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.To extent of visualization the CSF spaces are appropriate for the patient's stated age with no midline shift. No 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.The visualized portions of the paranasal sinuses demonstrate mild mucosal thickening. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
MRI of the IACs is within normal limits.
