Dizziness. There are numerous T2 hyperintense foci in the cerebral white matter and basal ganglia. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The skull, paranasal sinuses, and scalp soft tissues are unremarkable. However, there is fluid within the left mastoid air cells. There are bilateral lens implants. There is also an incompletely characterized T2 hyperintense focus in the left parapharyngeal space.
1. Chronic lacunar infarcts and small vessel ischemic disease, but no evidence of acute infarct.2. Nonspecific fluid within the left mastoid air cells may represents mastoiditis.3. Incompletely characterized T2 hyperintense focus in the left parapharyngeal space. Dedicated imaging of this region may be useful for further evaluation.
