If so, what was the treatment in your case? I have had some found 'by accident' on ultrasound. Very small but have slightly grown over a year, but GP is totally unconcerned, but they bother me. Only psychologically - no physical problems with them but they worry me.
I've got one - it's quite big, and attached by a sort of thread so sometimes it sort of plugs the duct and causes me problems, then it will be fine for ages when it has sort of moved out of the way. I have it measured every six months to make sure it isn't growing alarmingly.
If it is causing no problems and your Gp is unconcerned, I wouldn't worry. mine was found because I was having gall bladder pain, so had an ultrasound.
Oh - treatment - I was going to have the gall bladder out when I was getting a lot of pain, but it has shifted position and seems OK atm. So I have left it. If it flares up again I'll have it removed. It is just monitored. I also have drugs to ease the pain if I get a GB attack (but haven't had one for ages touch wood)
