Mass emerging from colon wall-what does this?

  • 8 year old M/N beagle presented for PU/PD and episode of collapse
  • PE shows an obese dog with markedly pendulous abdomen
  • PCV/TP are wnl.  Chemistry profile shows a slightly elevated ALKP.  rDVM wants to rule out Cushing’s.

    • Abdominal US done under telazol/ketamine/xylazine sedation shows a large, cavitated mass in the mid to caudal left abdomen.  It appears to be originating from the wall of the descending colon and growing outward.  The bladder is markedly distended.  The adrenal glands are normal.  There is some hepatomegaly with normal parenchyma.
    • FNA’s of the mass are pending. Cysto urinalysis is also pending.
    • Any ideas as to what does this and if it is related to the PU/PD?  My primary differential for the mass is a leiomyosarcoma.

Its likely an abscessing

Its likely an abscessing carcinoma or round cell tumor. Bad bugs live in the colon and when the wall is infitrated bacteria can embed into the wall and abscess. Subtotal colectomy in his future.

Can also consider focal

Can also consider focal foreign body perforation with granuloma formation.
