Any thoughts on this x-ray? I posted about my bearded dragon a few months ago. His phosphate, calcium and potassium is now elevated (can post blood work if needed). I suspect either kidney disease or neoplasia based on blood work.
There is a round structure in the cranial coelom that I don't know what is. He is eating and defecating normally, but losing weight.
