Hi...I was diagnosed with MG in 1998 and had my thymus removed....after 10 yrs, I finally went into remission,however symptoms started to return in October of 2014. I saw my new neurologist 2 days ago 5/12/2015 and he asked if I'd had any scans done to check for a regrowth of my thymus....which I have not. He stated that yes, it can grow back...
