 MRI better demonstrates mild diffuse volume loss with a somewhat more predominant frontal, and less so adjacent parietal, atrophy pattern. The temporal lobes by MRI do not appear disproportionately atrophied.Patchy subcortical and periventricular white matter T2 hyperintensity correlates with previous CT hypodensity, compatible with chronic small vessel ischemic disease.The ventricles and sulci are unchanged in size or shape. The cerebellar tonsils are in normal position. There are no masses, mass effect or midline shift. Redemonstrated is an enlarged, empty sella. There is no evidence for intracranial hemorrhage or acute cerebral, brainstem or cerebellar infarction. No diffusion-weighted abnormalities are identified. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. Mucosal thickening is present within the right frontal sinus, right ethmoid air cells, and bilateral inferior maxillary sinuses. The remaining paranasal sinuses and the mastoid air cells are clear.
