Had cryptogenic stroke, MRI showed increased T2 signal in subcortical white matter. What is ischemic gliosis?

I suffered a cryptogenic stroke about 18 months ago. After experiencing familiar symptoms on one side, I went to the ER. The MRI was normal with the exception of a few very small areas of increased T2 signal in the subcortical white matter . The reports goes on to say this could be benign or represent areas of ischemic gliosis . I am trying to understand what the ischemic gliosis might mean.

Thank you for posting your query.

I would like to reassure you that the MRI brain findings in your case do not represent any serious abnormalities.

Ischemic gliosis refers to old areas of brain affected with lack of blood flow. Ischemia means lack of blood flow to brain, and is suggestive of small brain stroke in your case. Gliosis refers to old healed area of brain stroke.

I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.

Wishing you good health,
