Thanks for your advice its help me to understand .about my situation .
Hello and hope you are doing well.
If the cavernoma detected in the MRI is compressing on the cerebrum then it should cause symptoms related to left hemisphere like difficulty walking, weakness, difficulty performing tasks and an inability to talk. So if it not causing any symptoms now, then the neurologist is likely to wait and watch. It needs monitoring at intervals to see that it is not getting bigger or causing compressive symptoms.
Hope this helped and do keep us posted.
