Any thoughts on this would be appreciated.
My corn snake developed a slight lump about 3 inches from his vent.
I went to the vet for an X-Ray and this is what we found…

It’s not a lump pushing out as much as it is something under the skin pressing in on its ribs. But there is nothing there. No mass or substance. Look closely at its rib bones. They go inward and then out again.
Anyone have any ideas?
