Vomiting young cat


– 10 month old FS Sphynx feline on and off history of vomiting, decreased appetite and wt loss

– neutrophilia on bloodwork otherwise viral testing NEG, biochem unremarkable

– rDVM placed pet on Clavamox with no improvement

– no history of fever

u/s thickened stomach wall, trace abdominal effusion and enlarged jejunal LN’s

DDx:  IBD/gastritis, FIP, lymphoma

Any other thoughts – proceed with LN FNA?

    Ah yes the ropey bowel

     
     

    Ah yes the ropey bowel cat wiht mesenteric lymphadenopathy.

    DDX parasites, IBD, FIP and maybe emerging LSA or MCT less likely because the LN are still egg shaped and echogenic as opposed to hypoechoic and distorted. This is a tendency and not an absolute by the way.

    FNA first and consider PCR or PARR for lsa if lymphoid population is the dx on cytology

    Given the history FIP is very possible here but may need full thickness and intraoperative ultrasound best to delineate the worst lesions for the dx.

  3. How thick were the bowel
    How thick were the bowel walls? Any muscularis thickening or bowel layer disproportionate thickening?

  5. Hi Marty
    The bowel wall

    Hi Marty

    The bowel wall thickness (SI) was normal and the layering was normal as well with no submucosal or muscularis thickening. That being said, the peristalsis seemed somewhat “stiff” to me in the jejunum. The stomach was the only part that was otherwise grossly abnormal on ultrasound.

    I am hoping to hear from the owner in order to recheck and perform a LN FNA. He is a VERY cautious pet owner. I also recommended chest rads but he did not want to do it because of the radiation. Doing an FNA on his pet will be a big deal -so we will see : )

    No worries! I use Marc D’Anjou’s book for reference ranges and have the normals in my Timeless system for easy reference when making my reports

  13. IN my experience its not the

    IN my experience its not the bowel thickness in cats thats important unless detail loss in a certain region but the thickness of the individual layers and inversion of the muscularis/mucosal ratio. You can have at times dramatic ratio changes and normal wall thicknesses. What this all means nobody knows lol but an item iof current studies.

  17. I wholeheartedly

    I wholeheartedly agree…overall thickness is not as important as proportionality of layering and when the muscularis gets thick (regardless of overall wall thickness), it’s significant – suggesting IBD vs. SC-LSA.  In most cases with muscularis changes the wall thickness is above 2.8mm which is when I call thickness abnormal.  2.2-2.5 is what I call normal, 2.5-2.8 becomes gray zone.  But I’ve seen cats with normally proportioned bowel layering that is 2.6-2.8 and I don’t get too excited.
