49-year-old male with altered mental status and seizure. There is no evidence of intracranial hemorrhage, or mass. Multiple patchy hypodensities in a periventricular distribution are consistent with small vessel disease, age indeterminate.Additional small focal hypodensity at the right frontal lobe, image 14 represents a cortical stroke which is new when compared to the prior study but of uncertain chronicity. An additional finding of a small atrophic gyrus in the high left parietal convexity represents an old small cortical calcific stroke which was present on the previous CT scan of 4/07. MRI is recommended to further characterize these findings.The ventricles and basal cisterns are normal in size and configuration.The calvaria and skull base are radiographically normal. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
Subcortical stroke as described above of uncertain chronicity, new when compared to the previous study. MRI is recommended for further evaluation if clinically warranted.
