There is a focus of hypodensity associated with volume loss located along the left occipital lobe which is centered in the the left calcarine cortex and lingual gyrus, not seen in the previous study associated with ex vacuo effect of the left occipital horn. In addition, small foci of a hypoattenuation are seen in the cerebellar lobes which were not present in the previous study. Since the prior exam the fourth ventricle appears somewhat larger. No evidence of acute intracranial hemorrhage. Periventricular and subcortical white matter hypodensities of a marked degree are present. Although this has not changed significantly since the 2014 exam, there is progression of the periventricular white matter hypodensities since 2004. There is loss of gray-white matter distinction in the thalami which appears to be chronic. Paranasal sinuses and mastoid air cells are clear. The visualized orbits appear intact.
