My MRI shows
It would have been much easier if you had told us at least your age as well some of your clinical history. None of the findings on that report is life threatening. The first part refers to remains of some old injury, sort of like small scars, not active anymore and hard to assess the origin, an infection in the past, or narrowing of small blood vessels leading to minor injury due to lack of blood flow. If over 65 the latter is more likely, should pay attention to factors like high blood pressure, diabetes, smoking, high cholesterol etc. which make you prone to more damage to blood vessels in the future. As for the microhemorrhage it's a small bleeding in the brain. Can also have several causes, report indicates a cavernous as the cause, it's a blood vessel abnormality, could cause small bleed or seizure, rarely life threatening only in particular localizations, doesn't look so in your case. Usually left as it is, rarely surgery or treatment for seizures.
