UPDATE!
Turns out that the shadow was pus collected on the turbinates from a molar root that was starting to fail. Tooth now out, wallet out as well.
Anybody know how fast these things grow? I just found out my horse likely has a largish one. Not blocking nasal passages yet.
It was kind of a coincidence we even found it. Noticed a bit of yellow snot a couple days b4 leaving town out for awhile and had vet out. Mass showed up on x-ray.
Surgeon said at his age (18) it could just be really funky mucous, so attending vet did a flush to see if anything washed out. 2 liters of saline and just a couple blobs of mucous.
We are doing antibiotics to see if they make a difference in the mass or not.
If not, I’m kinda bummed. The surgery sounds brutal, albeit it likely curative if it is a cyst.
However,
a) this horse is REALLY stressed about being in an unfamiliar place - stops eating and drinking, and sweats up bad in the trailer - and if we got into a back and forth to clinic for follow up’s I think it would trash his brain.
B) he has an arthritic stifle, both have had ligament splitting, and he has arthritic hocks. Vet says if he stands around mush both stifles will start slipping again.
C) add to all that, between monthly legend and arthritic every 9 mos or so to keep him comfortable, he costs almost as much as his board again.
Am inclined to put him on something to thin the mucous out for 6 months or so and take another set of x-rays to see how fast the damned thing is growing, but I don’t know if that is a rotten idea or not.
