Hello. I read your question and understand your concern. The most important thing in your history is you not having neurologic problems. The lesions seen probably on a radiologix exam may have probable causes. If you perform or have performed an MRI this would help a lot understanding the nature, especially a radiologic follow up ti see if there is any progression. Without these information it is difficult to make any consideration.But remember on the radiologic exam one can also find incidental findings with little or no significance. Wishing you good health
