This 10-year-old FS Doberman Pinscher presented for anorexia and weight loss. The physical exam was unremarkable other than mild dehydration and mild cachexia. CBC and blood chemistry analysis demonstrated mild regenerative anemia, moderate leukocytosis with a left shift, mild hypoalbuminemia and hypomagnesemia. The radiographs demonstrate mild ascites with poor organ detail.

Case Study
Intestinal Adenocarcinoma in a 10 year old FS Doberman Pinscher dog
Sonographic Differential Diagnosis
Obstructing annular duodenal wall mass with resultant gastric mechanical ileus consistent with neoplasia, most notably adenocarcinoma. Granulomatous disease is considered less likely.
Image Interpretation
The long axis image reveals marked, circumferential, symmetrical duodenal wall thickening with significant loss of mural detail (arrow) (Image and video 1.) The stomach is moderately distended with echogenic fluid (large arrow.) Two ovoid upper gastrointestinal lymph nodes are also enlarged (small arrows) (Video 2.)
DX
Intestinal adenocarcinoma
Outcome
The patient was euthanized due to poor prognosis.
Clinical Differential Diagnosis
GI pathology – Neoplasia, peritonitis, granulomatous disease, intestinal obstruction/perforation.
Sampling
A 16ga US-guided biopsy of the intestinal mass revealed adenocarcinoma (Video 3.)
