MRI tell exact location of a fibroid? Before surgery fibroid was on top of uterus during surgery found to be under cervix fibroid wasn't taken out

It should. An MRI will show exactly where fibroids are, and they will not move. It is likely, however, that you have more than one fibroid (most people who have them have multiple) and perhaps the fibroid near the cervix was not removed. It is hard to give a better answer to this question without seeing the actual images of the fibroids. .
