[quote user="Katie Blackburn"]The other finding was slightly harsh respiration, so whilst we were imaging his foot I took some views of his thorax. I can see a soft tissue density cranial to the heart on the lateral and a small mass just to the Left of the mediastinum on the DV. any ideas greatly appreciated.[/quote]

I'm wondering if what we're seeing is changes to the cardiac silhouette caused by enlargement of the pulmonary artery?

Replying to me own post! I've been reading through the notes from some CPD on cardiology I did a couple of weeks ago, and there is mention of aortic bulge on the cardiac silhouette as an incidental finding in older cats.

Hypertrophic osteopathy (aka Marie's disease)

Do you have an AP view, which should show characteristic changes? Since the entire leg isn't AP I'm just wondering whether a very slight rotation may be disguising early new bone formation?

If it's genuinely a purely soft tissue swelling, are there 2 seperate conditions?

On my phone so struggling a little with the films. Did you send the fna off to a lab for cytology? I had a similar-ish case that had haemangiosarcoma. (We found the probably primary in the chest when met hunting but he presented just with an odd distal limb swelling)
