Senior cat with large intestinal mass and hyperechoic mesentery: peritonitis? carcinomatosis?

Senior cat with large intestinal mass and hyperechoic mesentery: peritonitis? carcinomatosis?

* 13 yo cat, weight loss, mild decrease in appetite, large abdomen. No fever.

* Leukocytosis (WBC 27) with neutrophilia 22251), monocytosis (3846), low albumin (2.2), low TP (4.8), mild increase of ALP (84). 

* Large (5.5cm long by 3cm wide) heterogeneous hypoechoic intestinal mass with total loss of layers: lymphoma vs carcinoma.

* All intestines are thickened with a prominent muscularis: lymphoma vs other.

* All intestines are thickened with a prominent muscularis: lymphoma vs other.

* Severely rounded hypoechoic mesenteric LN (8mm wide) due to neoplasia vs reactive.

* Scant anechoic peritoneal effusion due to GI neoplasia vs FIP (unlikely given age).

* Large liver, GB sludge.

* Hyperechoic almost nodular mesentery everywhere. Do you think it is due to peritonitis? steatitis? carcinomatosis? (or lymphomatosis?)

* Pancreas: hyperechoic fat around the R pancreas/duodenum. Pancreatitis? pancreatic tumor?

* Owner declined FNA of mass/LN. I would recommend steroids for the neoplasia, but I am concerned about the possible peritonitis. P ate with appetite after the scan.

Thank you for your help!

Yikes !! Ugly intestinal mass

Yikes !! Ugly intestinal mass and ill defined omentum wiht localized free fluid. Intestinal lsa or similar extending into a lymphomatosis scenario. FNA the int mass and start chemo may respond.

Thanks for your input! What’s crazy is that the cat went straight to her food bowl after the scan and ate a full meal of a/d! Cats…
