I was in a horrible car accident back in 2008... when they did a brain scan everything came back ok but there was a notation on the report that the pituitary gland had " a somewhat thinned appearance " any ideas on what would cause that... should there be any concern? Doctors have never addressed this notation and I only know about it because of the notation on the report..... Currently having issues with the thyroid and was wondering if there could be any connection to a " thinning" pituitary gland... have researched online but can't find anything on the topic ... thank you for any info
