R/O FB vs pancreatitis vs other
1. Intestinal Mass – the findings are moderately-severe – DDx: adenocarcinoma vs. infiltrative neoplasia (lymphosarcoma vs. mast cell tumor) vs. feline gastrointestinal eosinophilic sclerosing fibroplasia (FGESF) vs. leiomyosarcoma vs. leiomyoma, dry form FIP possible but less likely.
2. Lymph nodes – the findings are suggestive of metastasis from the intestinal mass – DDx: infiltrative neoplasia (lymphoma vs. mast cell vs. other) vs. IBD vs. infection vs. reaction vs. metastatic neoplasia
Most loops of the intestines are WNL – normal bowel layering, wall thicknesses and motility. No mucosal stippling or disproportionate layering appreciated. There is a large hypoechoic heterogeneous mass measuring ~2cm involving the mid-jejunum in the lower right quadrant. The mass is well-circumscribed but the jejunum leading up to the mass has abnormal thickening of the muscularis layer and tapers to normal. The layering in the mass is obliterated and the mass is mildly erupting into the bowel lumen. Hyperechoic ill-defined reactive mesentery is associated with the mass suggestive for an aggressive transumural pathology with associated inflammation/peritonitis. Multiple mesenteric lymph nodes are moderately-severely enlarged and abnormally shaped having homogenous hypoechoic echogenicity.
Biopsies recommended to accurately define the type of disease present.
Consider surgical resection with histopathology and appropriate chemotherapy. Prognosis is very guarded.
