You can see abcess with laminitis, but it's also possible to incorrectly diagnosis laminitis when it's an abcess. With the initial onset of laminitis there may be no changes on x-rays etc and abcesses don't show up on x-rays as well though occasionally a vet may see something that looks suspicious for an abcess. So, you see it's rather a "best guess" game based upon symptoms, history and examination finding for either laminitis or abcess. And while laminitis generally presents in both front feet, it can also present as both hind feet, or only 1 foot.
