It shows the folly of taking just one view!

I am struggling to pick up much wrong on the lateral view and would have missed a pretty dramatic lesion evident on the other view!

Thanks David - I missed the fissure lines completely :)

I agree with Rajat, only thing to add would be there is a mild amount of effusion on the RHS visible on both views but fissure lines prominent on DV caudally.

The mass would have been easy to see with echo (especially with effusion) and sampled with a blue needle if owners wanted to pursue.

I just typed an answer then lost it aaghh so here it is in short-

I see a well positioned well collimated rad. It may be a bit over-exposed..or it may just be the pic.

The cardiac silhouette is normal

There is a mass lesion donut shape in the R middle lobe (or thereaboutS) confluent iwth mediastinum and cardiac silhouette - on DV - vaguely visible on the lateral too (with retrospectoscope!)

There is generalised radiolucency in most of the right hemithorax. The pulmonary vasculature is very very small - the caudal lobar artery and vein they are tiny and thready compared to the left side. There appears to be hyperinflation but this could just be a combo of incrsd effort, peak inspiration and pulmonary oligemia (can't tell you how long I've waited to use that word - nerd alert!! )

So I reckon your cat has a pulmonary neoplasia (primary) along with massive PTE and cardiogenic shock secondary to it (from yr description)resulting in hypothermia tachypnoea etc.

The prognosis is very poor so PTS wascorrect IMHO...

BTW - any lesions on the toes? Lameness preceding few days?

Anyone else got any thoughts?
