Canine Transmissible Venereal Tumor

  • 2-3 year old stray mixed breed mn dog with recently diagnosed Canine Transmissible Veneral Tumor
  • He has mulitple growths on his penis and a bloody prepucial discharge
  • The ultrasound is part of a met check to see if the dog is suitable for adoption (by a veterinarian of course)
  • Vincristine tx was started the day before this scan
  • Abdominal US shows a mildly enlarged prostate (this dog was recently neutered)
  • No enlarged lymph nodes, splenic or liver mets are seen

    • No enlarged lymph nodes, splenic or liver mets are seen
    • The kidneys look “different” to me-Instead of a smooth renal cortex with a sharp delineation to a hypoechoic medulla, I am seeing lots more nodular “structure” and echogenic patches in the renal cortex and medulla.
    • Are these battle scars from his life as a stray?  Is this normal variation (I usually scan old dogs with loss of detail). I want to be sure there is no evidence of CTVT metastases, especially with the bloody discharge. 
    • I am unable to upload an avi clip as the files are too big.

  1. The contour looks smooth. The

    The contour looks smooth. The cm junction is a bit nebulous but may be the angle or the settings. The CM ratio is 1:1. They dont look bad to me and if no urinary sediment or prtoeinuria they are likely normal /stable maybe age related. Video may show more of what you are seeing. Usually when there are cortical changes infarcts and such some level of capsular deviation/retration occurs, even minimally and I don’t see that here.

  3. It would very most unusual

    It would very most unusual for a TVT only to metastasis to the kidneys. Spread to the kidneys is report but it is part of disseminated spead to various organs. Consider looking at a urinalysis and renal parameters on serum biochemistry to get a better idea of what the animal’s renal function is.

  5. Thank you Dr. Lobetti.  Renal

    Thank you Dr. Lobetti.  Renal parameters were normal. I have now successfully converted the videos to mp4 format and uploaded them.
