To me, this sounds like a lot of fuss over nothing. It does not say that the DIL told her own mother about the scan, it could have been that after the scan and phone call she said lets not tell anyone about the placenta being low, so the son asked his mother not to say he had already told her.
It would seem that you do not like each other, that being the case then I can understand why she does not visit you. If you want to see your grandchild then arrange it with your son, if he wants you to see the child he can bring him to visit you.
There was no need to say you have helped them financially, the money does not buy you anything, You want them to see you because they want to not because of what you have given them.
