Female, 65 years old, with bilateral hearing loss, right more than left, subacute. Images are distorted by artifact arising from the scalp and from motion. Within this limitation, the following observations are made.No definite evidence of restricted diffusion is seen, though the diffusion weighted images are particularly degraded superiorly.Patchy periventricular T2 hyperintensity is demonstrated in a bilateral symmetric pattern. No mass-effect or parenchymal edema is seen. No evidence of acute intracranial hemorrhage is detected, though again, susceptibility weighted images are particularly degraded.Without the benefit of IV contrast, the internal auditory canals are normal in caliber and the cochleas show relatively normal morphology. The remainder of the inner ear structures are not well appreciated due to artifact. The cranial nerves arising from the brain stem are also not well visualized.
1. Limited examination due to distortion along the scalp and motion.2. No definite evidence of an acute intracranial abnormality is seen. Patchy white matter signal abnormality is nonspecific but may reflect chronic small vessel ischemic disease.3. Dedicated imaging of the inner ear structures is fairly limited due to the artifact noted above. The internal auditory canals and cochleas seem to be normal. The remainder of the inner ear structures are not adequately visualized, nor are the brainstem cranial nerves.
