Hello
This is Kenya an 8 year old FS lab who has a recent history of vomiting 2 x weekly and weight loss with normal bloodwork.
We performed an abdominal US and found a 1cm round anechoic lesion with a hyperechoic center that extended to the border of the lesion. It appeared to be ventromedial to the pylorus. I can not see it attached to anything except the fat.

I was hoping for some opinions on what it might be and whether it can account for the symptoms. FNA is our next but would like sonopath’s opinion prior to proceeding. Rest of US appeared normal to us.The first few clips are to try and give some perspective on location.
Thanks. Brent

I think this may be an enlarged LN, and if so, has neoplastic criteria with an increased S/L axis ratio and inflammation at the periphery but would need to sample to confirm – which you may be able to do showing its location. Will see what others have to say : )

Thanks!
I was told that
Thanks!
I was told that unattached round objects in the abdomen were usually LNs so your probably right. I just haven’t seen one look this way before.
I’m not familiar with S/L ratio? Can you let me know what that means? Thanks. Brent
The S/L axis ratio refers to
The S/L axis ratio refers to ratio of the measurement of a LN in its short and then long axis. I believe there was a paper stating that an abdominal LN with a S/L axis ratio of <0.5 is more likely to be reactive and anything >0.5 is more likley to be neoplastic, which just really means big round hypoechoic LN’s are more concerning for neoplasia than long, fusiform ones. It’s definitely not perfect due to the normal variation of size in LN’s and there is alot of overlap between reactive and neoplastic LN’s – biopsy is still the only way to know for sure.
yes definately a LN. Note the
yes definately a LN. Note the round capsule. This is th eepigastric LN I beleive and usually happnes when the stomach has somethign goign on in it. You will see this up in IBD cats a lot. In dogs I get worried about LSA or gastric carcinoma or hi this maybe helocobacter. Its a bit rounded but not distorted so likely reactive LN. Will need to use the corkscrew technique to get a good fna sample.
Thank you for the posts. Much
