A 4-year-old FS DSH cat was presented for intermittent vomiting over the course of the last few months. Recent blood work was unremarkable. The only significant finding on abdominal radiographs was a full colon.

Case Study
Lymphoma in a 4 year old FS DSH cat
DX
Intestinal lymphoma, high grade, duodenum
Sonographic Differential Diagnosis
Inflammatory or neoplastic gastrointestinal disease.
Image Interpretation
Image 1: Proximal duodenal thickening immediately distal to pylorus Video 1: Duodenal thickening distal to pylorus showing loss of mural detail and ill-defined, somewhat hyperechoic, possibly reactive mesentery in the associated tissue.
Outcome
The owner consulted with an oncologist but declined chemotherapy. The pet was started on prednisone, Pepcid and Carafate. Six months later the pet was re-evaluated for anorexia and lethargy and at which time was euthanized.
Comments
This duodenal lesion was very subtle and emphasizes the need to focus on loss of mural detail as well as the need to image the entire organ system. This small lesion was responsible for the clinical presentation in this pet. Such a lesion could have easily been missed owing to gastric or colonic artifact. The lesion was also identifiable by means of recognizing the + Murphy sign presented by the patient when imaging this region indicating perceived pain.
Clinical Differential Diagnosis
IBD, intestinal lymphoma, dietary hypersensitivity, GI tract motility disorder, intestinal helminths
Sampling
Full thickness surgical biopsy: high grade lymphoma
