What does this mean in laymans terms? (results of MRI of brain)?

There is a focus of increased signal intensity on the T2 weighted images within the right occipital periventricular white matter. This is nonspecific in appearance and could be due to ischemic change from small vessel disease, demyelination, or nonspecific gliosis.
There are no other areas of abnoral signal intensity identified. No cortical infarctions are identified or acute subcortical infarcts.
The ventricles & cortical sulci are normal in size and configuration.
There are no mass lesions seen or areas of abnormal enhancement.
IMPRESSION:
Nonspecific white matter abnormality in the right occipital periventricular white matter.

It is important that you ask this question to a doctor. My impression is that there is some focus spot there but they don't know what the cause is. You may want to ask your doctor:

1. How common is it to have these lesions in the occiptal white matter?
2. Do I need to have a second scan in the future to see if it has gotten worse?
3. Will I go blind from this? What is the chance that it will lead to any complications? (sight / memory function / etc)

There is one small area of the brain that is abnormal. The radiologist cannot tell from the MRI whether it is from a very small stroke or from something else. Everything else looks good.
