69-year-old female with a history of right basal ganglia stroke now with lethargy and confusion. Evaluate for hemorrhagic conversion. There is no evidence of intracranial hemorrhage, extra-axial fluid collection or mass. There is no mass effect or midline shift. There is a focal area of hypoattenuation in the right MCA perforator distribution in the right basal ganglia and right anterior limb of the internal capsule which appears more well defined and correlates to a subacute infarction previously demonstrated on MRI. There is no significant associated vasogenic edema.Redemonstration of nonspecific moderate periventricular and deep white matter hypoattenuation. These findings are most consistent with age indeterminate small vessel ischemic disease.The ventricles and basal cisterns are normal in size and configuration. The calvaria and skull base are radiographically normal. The visualized mastoid air cells are within normal limits. Again seen is a moderate mucosal thickening of the maxillary sinuses which appears unchanged when compared to the previous study.

These findings are most consistent with age indeterminate small vessel ischemic disease.3. Mild mucosal thickening of the maxillary sinuses bilaterally, unchanged.
