Foramen magnum/jugular lesion

Hi! A 6mm lesion in the foramen magnum/jugular was recently found on a CT. The radiologist said “possible meningioma”. I am having a MRI w/w/o contrast on Thursday. The research I have found said that this is a problematic area because of all the nerves and blood vessels as well as difficulty accessing for surgery. I assume that it will be a watch and wait situation. Has anyone had a similar situation? Any information that you are willing to share about your experience would be very helpful. Thanks!
