We noticed a few weeks ago that Luna's left front leg wrist joint (distal radius) looked larger than the right leg. At first I didn't think much of it, I have an enlarged thumb joint from having Lyme as a kid so I was thinking - she had that mystery but mostly likely tick borne illness in the spring so maybe she's like me and just has an enlarged joint/mild arthritis now.
But then I started googling and didn't see a lot of potential explanations on the cause of an enlarged joint in dogs and osteosarcoma kept popping up as happening most frequently in middle aged dogs but incidence also increased between the ages of 1.5-2 years of age and she's in that window.
I wasn't quite loosing sleep yet because she only limped for literally a couple seconds after jumping off the bed one morning 4 days ago. Other than that, it doesn't appear to cause her any discomfort and I've read that osteosarcoma is typically very painful. Anyway, we took her in tonight for x-rays and the vet said she doesn't think it's cancer because it's typically on the long bone, so this would be an unusual presentation and she's not limping, nor is it tender to the touch. But she doesn't feel that she can rule it out so she's going to send the x-rays out to radiology for review and I had her do a bone aspiration so that will be sent out too.
These are the X-rays. Has anyone ever seen osteosarcoma on a tiny bone on the foreleg?
