Is it possible for a mare to have a fluid filled uterus and fetal membranes seen on Ultra Sound and there be no foal in the sac?

Anything is possible... however, it would be unusual, and if the mare you are checking is between about 60 and 150 days of pregnancy, the most likely thing is that the fetus is over the pelvic brim and into the abdominal cavity. and out of reach of the ultrasonographer. If that is the case, it should become visible/palpable again after about the 150 day mark.

Thanks Jos, we dont know exactly how far along she is, she is a maiden and a mini, and she is between 178 and due any time. One possibility we didnt see a foal is because we couldnt get the prob in very far as the vet could only use 2 fingers and had to hold pressure on the probe.
If she was at least 178 days would it be possible to only see the uterus and the membranes? I would think if she were closer to due we would see foal parts. But maybe not if we couldnt get the probe in far enough?

If the fetus were lower down in the amniotic sac, then you might not see it.

I would recheck and/or run an estrogen assay.
