The patient is a feline DSH, NM, 10 years. The patient has intermittent vomiting and has lost 2 pounds in the past two months. Abdominal radiographs show slight accordion pattern.

Intestines – the findings are severe – DDX: inflammatory bowel disease vs. infiltrative neoplasia (small-cell lymphosarcoma vs. mast cell tumor – strong suspect IN THIS CASE) vs. dry FIP vs. fungal (histoplasmosis). Inflammatory bowel disease in cats can be chronic and longstanding, but in many cases will transition into small-cell lymphosarcoma and it is not possible with ultrasound alone to determine in this
case whether the disease is benign or infiltrative.
Many to most loops of intestine are prominent and mildly to moderately thickened measuring 3.0-4.0mm (normal wall thickness ~ 2.2-2.5mm). Many have abnormal layering with prominent thickening of the muscularis layer through and some loops have large fusiform mass lesions that are hypoechoic and in the
mucosal layer. These masses are well circumscribed and localized to one side of the bowel loop (non-circumferential). A large section of the ileum has this mass lesion. Multiple mesenteric lymph nodes are mildly enlarged and normally shaped having homogenous hypoechoic echogenicity. The fat surrounding the mesenteric lymph nodes is severely hyperechoic.
The patient was lost to follow-up
Neoplasia, IBD, infectious, foreign body.
Fine-needle biopsies of the mass lesions in the mucosal layer of the intestines were collected and submitted> LN: reactive lymphocytic hyperplasia. Intestinal wall: Lymphoma small cell
