  • BW 6 months ago mild anemia and slt low Alb.
  • BW Today…. Hct 17%, WBC 9,000, Neut 48%, Lymphs 51%.  BUN 48 H, Creat high N.

Didn’t stick this, whatever it is…. it’s my own cat, I can knock her out again if needed.  Figured I’d wait and see what spleen and liver showed.

Thank you!  Karen

  1. Not definitive but I would

    Not definitive but I would guess an echogenic perinephric lymph node, focal area of steatitis, or some type of granuloma. Its not shadowing so it doesnt look like a Bates Body. I dont think its a mass. The renal sinus in that kidney appears hyperechoic, possibly inflamed, so I wonder if its an extension of that. 

    • Thanks Mac!  That makes

      Thanks Mac!  That makes sense.  Thank you for running through your thought process on it!

      I ended up sending the case in.  Eric read it out very similar to that…. possible LN?

    • Ah yes, important details! 

      Ah yes, important details!  See below.  Pathologist suggested PCR testing (may pursue that today, I have my slides) and I’m getting chest rads done this morning as there was a Comet Tail pattern of the lungs through the diaphragm.  🙁

      I’m open to any suggestions Mac.  I may also do an Internal Med Consult depending on what the rads, CBC path review, PCR show.

      INTERPRETATION OF THE FINDINGS & FURTHER RECOMMENDATIONS

      Liver – Hepatocytes with cytoplasmic granularity and increased numbers of lymphoid cells

      Spleen – Large numbers of round cells suggestive of lymphoma

      Thanks!!

       

  2. Ugh sorry to hear that Karen.

    Ugh sorry to hear that Karen. Pending chest rads, I agree to further clarify the lymphoma and internal medicine or oncology consult with chemo. I dont see it in the kidneys.
