The gastrointestinal tract revealed variable areas of small intestine with some minor loss of detail and peri-intestinal, hyperechoic inflammatory disease. The most dramatic inflamed intestinal tract was noted in image 1. This is assumed to be jejunum. Ideally this portion of small intestine would be surgically resected. The peri-serosal, hyperechoic, inflammatory pattern would suggest transmural pathology. Primary differentials of this portion of intestine include lymphoma, mast cell disease, dry form FIP or complicated inflammatory bowel disease and spontaneous necrosis. Intraoperative ultrasound would prove ideal in this case. Renal and hepatic biopsies would be ideal at that time. Regional lymphadenopathy was noted in the mesenteric root and measured 0.86 x 0.37 cm. Other variable areas of small intestine appeared largely normal with only minor thickening of the muscularis.
