Dementia. Many of the sequences are degraded by patient motion. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There has been progression of diffuse areas of cerebral and pons white matter T2 hyperintensity. The ventricles and sulci are diffusely enlarged. There is a partially-empty sella. There is no midline shift or herniation. The major cerebral flow voids are intact. The skull and scalp soft tissues are grossly unremarkable. However, there is diffuse paranasal sinus mucosal thickening and fluid within the maxillary sinuses. There is fluid signal within the mastoid air cells as well. There are bilateral lens implants.
1. Diffuse cerebral volume loss without a pattern suggestive of a specific neurodegenerative syndrome.2. Interval progression of nonspecific diffuse areas of cerebral white matter T2 hyperintensity, which may be related to chronic small vessel ischemic disease. 3. Findings suggestive of acute sinusitis and right mastoiditis.
